Two Cases of Azygos Lobe With Normal and Aneurysmal Azygos Vein on Computed Tomography.

Abstract

Azygos lobe represents normal variation of the pulmonary anatomy. Aneurysmal of azygous vein is very rare and patient remains asymptomatic. Here we report two cases of azygos lobe; one with normal azygous vein diameter and another case with aneurysmal azygous vein. Both cases were incidental detected during Computed Tomography scan. Fusiform aneurysm of azygos vein within azygos fissure has never been reported.
