Case contributed by Dr Safwat Mohammad Almoghazy


A known case of ovarian cancer under work up.

Patient Data

Age: 55 years
Gender: Female

Azygos lobe and fissure are incidentally noted (normal variant).

Case Discussion

An azygos lobe is created when a laterally displaced azygos vein creates a deep pleural fissure into the apical segment of the right upper lobe during embryological development. It is not a true accessory lobe as it does not have its own bronchus.
