Azygos vein aneurysms are extremely rare, and their pathogenesis is not clear. The overwhelming majority of patients have no obvious clinical symptoms and are found to have the disease by physical examination or by chance. There are few reports on the diagnosis of and treatment strategy for this disease. Moreover, the choice of therapeutic schedule and the treatment window are controversial.
We report a case of azygos vein arch aneurysm in a 53-year-old woman. The patient had symptoms of back pain, chest tightness, and choking. Enhanced chest computed tomography showed a soft-tissue mass in the right posterior mediastinum, which was connected to the superior vena cava. The enhancement degree in the venous phase was the same as that of the superior vena cava. The patient received video-assisted thoracoscopic surgery. After the operation, her back pain disappeared, and her dysphagia and chest tightness were also significantly relieved. The postoperative pathology confirmed hemangioma. The patient was discharged on the seventh day after surgery without any comp-lications.
Some patients with hemangioma of the azygos vein arch may experience dysphagia and chest tightness caused by the tumor compressing the esophagus and trachea. Enhanced computed tomography scanning is vital for the diagnosis of azygos vein aneurysms. In addition, despite the difficulty and risk of surgery, thoracoscopic surgery for azygos vein aneurysms is completely feasible.
Core Tip: Azygos vein aneurysms are extremely rare. We present a patient with hemangioma of the azygos vein arch who experienced dysphagia and chest tightness caused by a tumor compressing the esophagus and trachea. The patient received video-assisted thoracoscopic surgery. We herein report the first case of a patient with choking symptoms due to the esophagus being compressed by an azygos vein aneurysm.
