[Azygos vein aneurysm forming a mediastinal mass].
Aneurysm of the azygos vein is a rare cause of mediastinal mass that is normally detected radiologically in asymptomatic patients. In some cases a diagnosis is made by noninvasive methods, such as computed tomography and magnetic resonance. However, in the present case imaging revealed what appeared to be a solid mass. When the mass had been excised by thoracotomy, the histopathologic diagnosis...

متن کاملAzygos Vein Aneurysm Mimicking a Calcified Lymph Node

متن کاملThe Abnormally Situated Azygos Vein
The azygos vein may be abnormally situated due to anomalous embryologic development. Its abnormal location is infrequent, but radiologic recognition is much easier than that of the normal vein. This vein, normal or abnormal, becomes distended in conditions with an elevated venous pressure, systemic or portal. Changes in the size of the azygos vein on x-ray are noted to parallel fluctuations of ...
