Popis: Abstract Intraluminal tumor in the azygos vein is a rare disease that can cause superior vena cava (SVC) syndrome. Radiotherapy and endovascular stenting with or without chemotherapy are reported to have a high clinical success rate for the management of SVC syndrome with malignancy, but a poor survival rate. Here, we report a 69‐year‐old man who presented with swelling of the face and upper extremities, who was diagnosed with SVC syndrome caused by an intraluminal tumor in the azygos vein. Enhanced chest computed tomography revealed an intraluminal mass with a filling defect from the azygos vein to the SVC, with no extravascular extension or dissemination of the primary tumor. Surgical resection of the mass en bloc with the azygos vein and SVC reconstruction was performed. A poorly differentiated carcinoma was diagnosed on postoperative pathological evaluation. Twelve months after resection, the patient was well with no signs of recurrent disease. This case highlights that surgical resection should be considered as a treatment of choice for the management of SVC syndrome caused by an intraluminal malignancy in the azygos vein.
