A female in her early thirties, non-smoker, with no known comorbidities, presented to the emergency room with multiple episodes of hemoptysis and exertional dyspnea for a week. She had no history of hemoptysis or any known lung disease in the past. Chest X-Ray revealed relatively small right lung with mediastinal shift to the right. CT angiography revealed right-sided absence of pulmonary artery with collateral supply (systemic to pulmonary shunt) from hypertrophied bronchial, internal mammary and intercostal arteries. She was successfully managed with therapeutic selective embolization of bronchial arteries to control the hemoptysis.
