Summary:A 37-year-old man was admitted to the hospital because of massive hemoptysis. A chest X-ray film showed decreased radiolucency in the right lower lung field. A chest CT scan revealed enhanced nodule medial to the right A8. Bronchoscopic examination revealed a narrowing of the right B8. During examination, he coughed up massive blood. Emergency intubation was done and a right lower lobectomy of the lung was performed. Histologic examination of the resected specimen revealed that the pulmonary arterial aneurysm perforated into the bronchus. After the operation, he developed persistent disturbance of consciousness by hypoxic encephalopathy and pyothorax. He was discharged very much improved on the 9th postoperative month. Peripheral pulmonary arterial aneurysm has rarely been reported. The establishment of early diagnosis and treatment is important in managing the rupture of pulmonary arterial aneurysm that can cause hypovolemic shock and acute respiratory failure.
