A 40-year-old man was referred for evaluation of cough of a few weeks duration and a history of recurrent respiratory tract infections for several years. Clinical examination revealed no abnormalities. Routine hematologic and biochemical evaluation were normal. Contrast-enhanced computed tomography of the thorax showed a hypoplastic right lung, hyperinflation of the left lung with cardiomediastinal shift to the right. Absence of the right pulmonary artery was noted and replaced by an extensive collateral network of hypertrophied vessels originating from bronchial, intercostal and mammaria interna arteries, and right arteria subclavia (Fig. A, B). Discrete bronchiectasis with thickened bronchial walls in a hypoplastic right lung was noted (Fig. C). A normal bronchial tree and normal parenchyma in the left lung was seen.
