The lobe of azygos vein, an uncommon malformation first described in 1777, has a reported incidence of 0.41%. It is an accessory lobe of the lung that may be occasionally confused with a pathological process such as a bulla, lung abscess or neoplasm. The anatomical basis for this variation is the failure of migration of azygos vein from the chest wall to its usual position in the tracheobronchial angle so that the invaginated visceral and pleural layers persist to form a fissure. In the present study, an azygos lobe was observed on the right lung of a 70-year-old male cadaver. The findings have been discussed in detail along with its ontogenic, phylogenetic, pathological, radiological and surgical implications.
