Abstract
We report a case of variceal changes of the azygos vein, hemiazygos vein, and paraesophageal collaterals presenting as bilateral posterior mediastinal masses in a patient with long-standing portal hypertension due to hepatosplenic schistosomiasis. The case is unusual because the varices were considerably larger than those usually encountered in portal hypertension. Dynamic CT allowed the diagnosis in demonstrating the vascular nature of these masses, which enhanced to the same degree as the other vessels. Noninvasive techniques, such as color Doppler sonography and MRI, may also be useful due to their multiplanar capabilities.
