Coronavirus disease 2019 (COVID-19) has become a massive epidemic affecting millions of people worldwide. The common radiological findings of COVID-19 are peripheral ground glass or consolidative opacities, but pneumomediastinum is a very rare finding of COVID-19, especially in patients not receiving mechanical ventilation support. Our aim was to present cases of spontaneous pneumomediastinum in two patients with COVID-19 and to discuss the potential mechanism underlying it.

A 45-year-old male presented with shortness of breath, cough,and chest discomfort. He reported positive test results for coronavirus disease 2019 (COVID-19) four days prior; this was confirmed by a second test administered at the hospital. Results of a chest CT, consistent with COVID-19 pneumonia, also revealed pneumomediastinum (PM). EKG showed ST elevations in the inferior leads with no reciprocal changes. Emergent cardiac catheterization showed that he had no stenosis in his major coronary arteries. His symptoms resolved after 25 days of hospitalization and the patient was ultimately discharged. This case highlights the importance of recognizing spontaneous PM as a complication of COVID-19 along with its uncommon presentation of ST elevation in order to prevent unnecessary invasive procedures.

Coronavirus illness 2019, commonly referred to as COVID-19, is a highly infectious disease brought on by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 was declared a universal pandemic in March 2020 by the World Health Organization and is a severe health issue with unprecedented morbidity and mortality rates. Both surgical and mediastinal emphysema have been seen in cases of critically ill COVID-19 patients in several hospitals in the Eastern Province of Saudi Arabia.

This was a retrospective, cross-sectional, multicentric study involving several hospitals in the Saudi Arabian Eastern Province. Data were collected from intensive care units (ICUs) in these hospitals from March 2 to August 2, 2020. The inclusion criteria consisted of all patients who tested positive for SARS-CoV-2 and were admitted to a critical care unit.

Thirty patients required thoracic consultation and management, including 26 males (81.3%) and 4 females (12.5%) (1:0.15) who developed surgical and mediastinal emphysema requiring thoracic surgery intervention. Most of the patients were on high ventilation settings, and the mean duration of ventilator support was 16.50 ± 13.98 days. Two patients (6.3%) required reintubation. The median positive end-expiratory pressure (PEEP) was 12 ± 2.80 cmH₂O with a median FiO2 of 70% ± 19.73. On average, thoracic complications occurred on day 3 (±6.29 days) postintubation. Ten patients (33.33%) experienced a pneumothorax associated with surgical emphysema (SE), 1 patient (3.33%) presented with only mediastinal emphysema; 17 patients (56.66%) with only SE, and 1 (3.33%) had mediastinal emphysema associated with SE. We noted a correlation between the duration of ventilator support, the length of ICU stay (P < 0.001), and the total length of stay (LOS) in the hospital (P < 0.001). Total length of hospital stay showed significant association with the onset of complications (P = 0.045) and outcomes (P = 0.006). A significant association between PEEP and the duration of ventilator support was also evident with a P value = 0.009 and the onset of complications (P = 0.043). In addition, we found a significant association between the group with pneumothorax in combination with SE, and their outcomes, with a P = 0.002.

Surgical and mediastinal emphysema in the critically ill patients are usually attributed to barotrauma and high ventilations settings. During COVID-19 pandemic, these entities were seen and the pathogenesis was revisited and some attributed its presence to the disease process and destruction on lung parenchyma. The associated with extended LOS and delayed recovery in addition to poor prognosis were seen. Their presence is an indicator to higher morbidity and mortality.

Background  Spontaneous pneumomediastinum (SP) is the presence of free air into extra-alveolar tissues within the mediastinum, without notion of trauma. This rare condition may occur as a complication of an underlying severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia. Higher rates of mechanical ventilation are reported in coronavirus disease 2019 (COVID-19) patients with pneumomediastinum.

Case Description  We report two cases of COVID-19 infected patients suffering from mild and severe SP and their outcome.

Discussion  The objective of this report is to review the literature about this condition. We discuss about the pathological pathways underlying this complication and how it reflects the severity of COVID-19 pneumonia.

Conclusion  Currently, it remains unclear if SP in SARS-CoV-2 pneumonia is a potential predictor of disease worsening, for it does not seem to be related with a higher rate of mortality.

We encountered the novel coronavirus infection as a pandemic in 2020. The infection started in Wuhan, China, and spread rapidly all over the world. CT scan has been used as an important diagnostic method in the detection of suspicious patients. One of the uncommon complications of coronavirus disease 2019 (COVID-19) is pneumothorax.

A 47-year-old smoker male with COVID-19 diagnosis, good general condition and no respiratory complaint, complicated by pneumothorax. He refused hospitalization. After educating him about the red flags and quarantine protocols, he continued treatment at home .Cap amoxicillin/clavulanic acid 625mg was prescribed for one week. A follow-up CT represented only small involvement of lungs. Pneumothorax was resolved spontaneously without any medical intervention and hospitalization. O₂ saturation was in normal range an there was no dry cough anymore.

According to our clinical experience, pneumothorax is resolved spontaneously in a COVID-19 case. Considering general status and hemodynamic stability, it is suggested to reduce invasive interventions in COVID-19 cases with pneumothorax.

Spontaneous pneumomediastinum (SPM) is a rare condition defined by the presence of air in the mediastinum in the absence of traumatic or iatrogenic injury. Although the imaging findings and complications of SARS-CoV-2 infection have been reported many times, there are few reports of the prevalence and outcomes of patients with SPM.

In this paper, we aimed to illustrate the different manifestations, management, and outcome of three cases of SPM in COVID-19 patients and provide an extensive review available literature.

Detailed report of patients' demographics, clinical presentation, management, and outcome of three cases of COVID-19 induced SPM seen in our institution was provided. Additionally, literature search was employed through March 2021 using Pubmed and Google scholar databases where a total of 22 articles consisting of 35 patients were included.

Statistical analysis of the reviewed articles showed that SPM in COVID-19 occurs in patients with a mean age of 55.6 ± 16.7 years. Furthermore, 80% of the 35 patients are males and almost 60% have comorbidities. Intriguingly, SPM in COVID-19 is associated with a 28.5% mortality rate. These findings are consistent with our case series and are different from previous reports of SPM in non-COVID-19 cases where it most commonly occurs in younger individuals and has a self-limiting course with a good outcome.

Therefore, SPM in COVID-19 patients occurs in older patients and is potentially associated with a higher mortality rate. Further studies are necessary to assess its role as a prognostic marker of poor outcome.

The incidence of pneumomediastinum (PNMD), its causes of development and its effect on prognosis in the coronavirus disease 2019 (COVID-19) are not clear.

Between March 2020 and December 2020, 427 patients with real-time reverse transcriptase-polymerase chain reaction-confirmed COVID-19 admitted to the intensive care unit were analysed retrospectively. Using receiver operating characteristic analysis, the area under the curve (AUC) for initial invasive mechanical ventilation (MV) variables such as initial peak inspiratory pressure (PIP), PaO₂/FiO₂ (P/F ratio), tidal volume, compliance and positive end-expiratory pressure was evaluated regarding PNMD development.

The incidence of PNMD was 5.6% (n = 24). PNMD development rate was 2.7% in non-invasive MV and 6.2% in MV [odds ratio (OR) 2.352, 95% confidence interval (CI) 0.541–10.232; P = 0.400]. In the multivariate analysis, the independent risk factors affecting the development of PNMD were PIP (OR 1.238, 95% CI 1.091–1.378; P < 0.001) and P/F ratio (OR 0.982, 95% CI 0.971–0.994; P = 0.004). P/F ratio (AUC 0.815, 95% CI 0.771–0.854), PIP (AUC 0.780, 95% CI 0.734–0.822), compliance (AUC 0.735, 95% CI 0.677–0.774) and positive end-expiratory pressure (AUC 0.718, 95% CI 0.668–0.764) were the best predictors for PNMD development. Regarding the multivariate analysis, independent risk factors affecting mortality were detected as age (OR 1.015, 95% CI 0.999–1.031; P = 0.04), comorbidity (OR 1.940, 95% CI 1.100–3.419; P = 0.02), mode of breathing (OR 48.345, 95% CI 14.666–159.360; P < 0.001), PNMD (OR 5.234, 95% CI 1.379–19.857; P = 0.01), positive end-expiratory pressure (OR 1.305, 95% CI 1.062–1.603; P = 0.01) and tidal volume (OR 0.995, 95% CI 0.992–0.998; P = 0.004).

PNMD development was associated with the initial P/F ratio and PIP. Therefore, it was considered to be related to both the patient and barotrauma. PNMD is a poor prognostic factor for COVID-19.

Spontaneous pneumomediastinum (SPM) is the collection of air within the mediastinal cavity, which is commonly described in the literature for mechanical ventilation and perforation of hollow viscera. Coronavirus disease 2019 (COVID-19) is a rare but salient etiology of this complication in the current pandemic. Here, we are narrating a case of a 46-year-old male, in whom COVID-19 pneumonia was complicated by SPM. The complication was identified on chest computed tomography (CT) and was managed conservatively, leading to a favorable outcome. SPM has undemanding management, but timely identification and appropriate treatment institution are crucial in this milieu. A literature search revealed similar cases of SPM in COVID-19 with different outcomes and the important ones are included in this report.

The incidence of secondary coinfections particularly fungal infections among severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not well described. Little is known of the complications that could be encountered in such conditions.

A 50-year-old Hispanic male who was a prior smoker presented with shortness of breath. He was diagnosed with SARS-CoV-2. He improved and was discharged with home oxygen. A month later, he presented with sudden onset cough and shortness of breath. Chest X-ray showed development of right-sided tension pneumothorax, right pleural effusion and an air-filled cystic structure. Computed tomography thorax showed findings suggestive of pulmonary coccidioidomycosis. Coccidioides antigen was positive, and fluconazole was initiated. For pneumothorax, a pigtail catheter was placed. The pigtail chest tube was later switched to water seal, unfortunately, the pneumothorax re-expanded. Another attempt to transition chest tube to water seal was unsuccessful. Pigtail chest tube was then swapped to 32-Fr chest tube and chemical pleurodesis was performed. This was later transitioned successfully to water seal and finally removed. He was discharged on a four-week oral course of fluconazole 400 mg and was to follow up closely as an outpatient for continued monitoring.

Pneumothorax is associated with a worse prognosis, especially with comorbidities such as diabetes, immunosuppression and malignancy. Suspicion for concomitant fungal infection in such patients should be high and would necessitate further investigation.

Subcutaneous emphysema (SE) and pneumomediastinum are rare complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). While SE is often non-fatal and usually self-remitting, pneumomediastinum can be fatal with high mortality rates depending on the underlying etiology. Here, we present the case of a 39-year-old otherwise healthy male who tested positive for SARS-CoV-2. The patient was treated with non-invasive mechanical ventilation (NIMV) and developed severe SE and pneumomediastinum which resulted in a fatal outcome. Although the exact pathogenesis could not be determined, the extensive lung injury caused by SARS-CoV-2 pneumonia along with possible barotrauma secondary to NIMV could have been the culprits in this case.

Early detection through careful observation of these potentially fatal complications in patients with severe coronavirus disease 2019 is crucial. Further studies determining the potential risk factors and incidence of SE and pneumomediastinum, especially in patients receiving invasive mechanical ventilation or NIMV, are needed.

Spontaneous pneumomediastinum is a rare complication of coronavirus disease 2019. The published literature consists mainly of case reports and small case series. There are still many questions regarding the pathogenesis, the prognostic significance and the implications on patient management. In our hospital, 3 coronavirus disease 2019 patients developed spontaneous pneumomediastinum: 1 on admission at the emergency department and the other 2 during hospitalization. In this study we describe their clinical course and computed tomography (CT) findings. All of them had severe disease according to the total severity score on admission CT. The management of pneumomediastinum was conservative and follow-up CT showed resolution in all patients. As the correlation between extension of parenchymal lung lesions and development of pneumomediastinum is still under investigation, we highlight the importance of reporting the severity score on chest CT in order to obtain more comparable results between different studies. Furthermore, in this tragic circumstance we also had the opportunity to familiarize ourselves with the otherwise uncommon occurrence of air along the bronchovascular sheaths (Macklin effect) and evaluate the ability of CT to detect it.

Spontaneous pneumomediastinum is defined as having an etiology that is not related to surgery, trauma, or mechanical ventilation. Precipitating causes of spontaneous pneumomediastinum include coughing, exercise, vomiting, infection, underlying lung diseases such as asthma, and illicit drugs. Symptoms include chest pain, shortness of breath, and dysphagia. A 54-year-old man presented with 2 weeks of shortness of breath, cough, and fever. He was admitted for severe SARS-CoV-2 pneumonia and acute hypoxic respiratory failure requiring non-rebreather mask. Chest imaging on admission showed bilateral peripheral consolidations and pneumomediastinum with subcutaneous emphysema. No precipitating event was identified. He did not require initiation of positive pressure ventilation throughout his admission. On hospital day 7, chest imaging showed resolution of pneumomediastinum and subcutaneous emphysema, and he was successfully discharged on oxygen therapy. Spontaneous pneumomediastinum is a rare complication of severe acute respiratory syndrome coronavirus 2 infection. Spontaneous pneumomediastinum is typically benign and self-limiting, requiring only supportive treatment.

Patients infected with coronavirus disease 2019 (COVID-19) on invasive mechanical ventilation were found to have high rates of barotrauma. Herein, we present five patients admitted to the intensive care unit between March and April 2020, who developed barotrauma as a complication of COVID-19 pneumonia. This series includes four males and one female with a mean age of 54 years, most without significant chronic comorbidities or former tobacco use. All were intubated for hypoxic respiratory failure due to the COVID-19 infection. The diagnosis of barotrauma was confirmed via radiography showing the presence of pneumothorax, pneumomediastinum, or subcutaneous emphysema on radiographic imaging. At the time, they were evaluated for convalescent plasma infusion, remdesivir, and interleukin-6 inhibitor. Each of the five patient's hospital courses were documented. The average number of days between intubation and subsequent barotrauma was 6.8 days with the mean length of hospital stay being 49 days. Three of the five patients passed away due to complications related to COVID-19. Due to the unknown nature of the virus, our findings add to the growing evidence that those infected, even without significant comorbidities, are at high risk for pulmonary complications and in-hospital mortality.

Iatrogenic pneumothoracis, barotraumas, and tracheoesophageal fistulae, especially after prolonged intubation, and tracheal stenosis are all entities involving thoracic surgeons' consultation and management. With the surge of COVID-19 cases particularly in the critical care settings, various types of complications have been observed that require intervention from thoracic surgeons.

A retrospective study was conducted in an academic healthcare institute in the Eastern Province of Saudi Arabia. We included all COVID-19 cases admitted to ICU in the period between March 15, 2020, and August 15, 2020, requiring thoracic surgery consultation and management. Non-COVID-19 critical cases and iatrogenic pneumothorax were excluded.

Of 122 patients who were admitted to ICU with COVID-19, 18 patients (14.75%) required thoracic surgery consultation and management. We discovered a significant association between the outcomes and reintubation rates and the rate of pneumothorax occurrence. The survival analysis showed improvement in patients who had thoracostomy tube insertion as a management than the group who were treated conservatively. On the other hand, there was a significant difference between the COVID ICU group who had thoracic complication and those who did not regarding the length of hospital stay.

Noniatrogenic pneumothorax, subcutaneous emphysema, and mediastinal emphysema are well-known thoracic entities, but their presence in the context of COVID-19 disease is a harbinger for worse prognosis and outcomes. The presence of pneumothorax may be associated with better prognosis and outcome compared to surgical and mediastinal emphysema.

Coronavirus disease 2019 (COVID-19) is caused due to infection by severe acute respiratory syndrome virus coronavirus 2 (SARS-CoV-2). It is highly infective virus resulting in recent on-going pandemic and causing multisystem involvement predominantly affecting respiratory system. The most common presenting symptoms are fever, dry cough and breathlessness. The role of Computerized tomography (CT) is crucial especially in those patient having negative (rRT-PCR) but with high clinical suspicion, for prognosis and follow up. CT imaging findings mainly consists of multiple patchy bilateral ground-glass opacity (GGO) with or without consolidation and interlobular septal thickening with a peripheral or posterior distribution, mainly involving the lower lobes, depending upon the stage of disease. We present two case report of high CT severity score COVID-19 infection on non-invasive ventilation (NIV) having rare complication of pneumomediastinum and subcutaneous emphysema apart from typical COVID pattern lung findings during their course of admission in the hospital.

COVID-19 is a relatively new and rapidly emerging disease. Given current knowledge of the disease process, it is of the utmost importance to gain further insight into its different clinical manifestations. In this report we describe three cases involving Hispanic males with COVID-19 all of whom developed pneumomediastinum during their hospital course. We want to emphasize the importance of this adverse event despite their non-smoking history and the exclusion of positive pressure ventilation. Frequent chest radiographs help with early recognition of this disease process. Early detection of pneumomediastinum is important as this could lead to worse morbidity if left unrecognized despite its usually benign nature.

As the global COVID-19 pandemic has progressed, awareness of uncommon presentations and complications has increased. The actual incidence of spontaneous pneumothorax was found to be 0.66%, or six patients out of 902 who tested positive in recently published literature of 3368 patients (Zantah M, Dominguez Castillo E, Townsend R, Dikengil F, Criner GJ. Pneumothorax in COVID-19 disease-incidence and clinical characteristics. Respir Res. 2020 Sep 16; 21 (1):236.). Of those six patients, only two (0.22%) were not associated with mechanical ventilation barotrauma or comorbid lung disease such as COPD. Here, we present a spontaneous pneumothorax and pneumomediastinum in a patient four days after he had been discharged from hospitalization due to uncomplicated COVID-19 pneumonia.

The first case of coronavirus disease 2019 (COVID-19) was declared in December in Wuhan, before becoming a global pandemic in a few weeks. Several complications of this infection have been reported. However, a spontaneous pneumomediastinum has rarely been described. We report the fourth case of this extremely rare complication in a 65-year-old male patient with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pneumonia, discovered during his therapeutic management by a CT scan control.

Coronavirus Disease 2019 (COVID-19) has rapidly spread worldwide. Numerous studies have shown its typical and atypical CT findings. We report one COVID-19 patient who presented with a transient pneumothorax, spontaneous pneumomediastinum (SP), as well as subcutaneous emphysema during hospitalization. Chest CT andclinical findings were discussed, and a literature review is presented. The probable cause of SP in COVID-19 was alveolar damage. Once pneumothorax and SP were present, the patient should be carefully monitored to prevent respiratory deterioration, especially when lung lesions are severe.

A novel coronavirus, SARS-COV-2, related infection is thought to have originated in Wuhan, China, in November 2019 but spread rapidly to be declared a global pandemic by the WHO in March 2020. The patients typically present with fever and shortness of breath. We describe a case of spontaneous pneumomediastinum at presentation as a complication of severe Covid-19 infection.

A 54 year old male patient with no history of smoking, asthma or other underlying chronic lung disease, presented to our emergency department with severe Covid-19 symptoms. His chest x-ray and CT scan on arrival at the emergency department, and prior to any intervention, demonstrated severe bilateral Covid-19 pneumonia complicated by a pneumomediastinum. The aetiology of the pneumomediastinum is thought to be a direct complication of severe covid-19 pneumonia in absence of any previous respiratory history or iatrogenic cause.

Spontaneous pneumomediastinum is a rare complication of viral pneumonia. Here we report a case of a 52 year old male who presented with a spontaneous pneumomediastinum in COVID-19 pneumonia, followed by a severe course of disease. We discuss the pathophysiological mechanisms underlying this association as well as its possible clinical implications as a marker of disease severity in COVID-19.
