Pulmonary aplasia is a rare bronchopulmonary foregut anomaly characterized by the presence of a rudimentary main bronchus in
the absence of lung and ipsilateral pulmonary artery. From 1762 there have been only 200 documented cases of lung aplasia which
is very less as compared to lung agenesis. This disorder is usually diagnosed in the infancy or early childhood but may be delayed
until adulthood in asymptomatic individuals or individuals without any associated comorbid anomalies. Here we report a case of a
28-year-old male who presented to us with mild respiratory distress and dry cough with a left radiopaque hemithorax in which the
diagnosis of pulmonary aplasia was completed with bronchoscopy and computed tomography scan of thorax.
