[A rare mediastinal-hilar pseudotumor: esophageal and azygos vein varices].
Mediastinal pseudotumors are present in less than 5% of patients with long-standing portal hypertension. These pseudotumors may be caused by para-esophageal collateral vessels or greatly dilated azygos or hemiazygos veins. Enhanced CT seems to be the best tool for the diagnosis and in evaluating the overall status of portosystemic collateral vessels. In this case report, MRI ruled out tissular mass by showing vascular signal.
