Abstract
BACKGROUND

Acute appendicitis with mesenteric vein thrombosis (MVT) is an uncommon condition and usually lacks specific clinical manifestations, which leads to a high rate of misdiagnosis or delayed diagnosis, especially when it is accompanied by other abdominal diseases. Prompt and accurate recognition is vital for treatment and prognosis.

CASE SUMMARY

A 37-year-old woman had a history of acute metastatic right lower abdominal pain, nausea, and fever. A contrast-enhanced computed tomography (CT) scan showed a filling defect in the mesenteric vessels. The patient was diagnosed with acute appendicitis complicated by MVT and was treated with anticoagulation and intravenous antibiotics. The follow-up CT scan showed full resolution of the thrombosis and inflammation.

CONCLUSION

Clinical awareness is essential for recognizing MVT, especially when it is accompanied by other common acute abdominal diseases, such as acute appendicitis. Contrast-enhanced CT is helpful for the diagnosis of MVT and is recommended for patients with acute abdominal diseases.

Core Tip: The article presents an uncommon clinical case of mesenteric vein thrombosis (MVT) complicated by acute appendicitis in a patient with no obvious risk factors for thrombosis. The patient was diagnosed correctly at an early stage and finally recovered after receiving anticoagulation and antibiotics. MVT is rare and difficult to recognize when it occurs with other acute abdominal diseases. Contrast-enhanced computed tomography is vital to its diagnosis. Therefore, clinicians should fully consider the possibility of this disease when treating patients with acute abdominal diseases and use appropriate diagnostic tests.
