Unilateral Lung Agenesis

Abstract

Unilateral lung agenesis is an uncommon developmental anomaly stemming from the incomplete formation of the primitive lung
bud. Its manifestation and onset vary widely, from asymptomatic instances to diagnoses in adulthood prompted by recurring
respiratory infections. Roughly half of these cases coincide with other congenital anomalies. A 23 years female diagnosed as
a case of treated pulmonary tuberculosis with right fibrocavitatory disease on the basis of chest x-rays despite negative smear
microscopy of sputum for acid-fast bacilli (AFB) referred to us with a complaint of shortness of breath on exertion. She was
evaluated further and on contrast, enhanced CT chest (CECT) was detected to have right lung agenesis, which was confirmed
on fiber optic bronchoscopy.
