[Intrapleural rupture of an pulmonary arteriovenous fistula]

Abstract

We describe a case of intrapleural rupture of pulmonary arteriovenous fistula and review is such cases previously reported in Japan. A 57-year-old woman was admitted with a sudden onset of right chest pain. Chest radiograph on admission showed right pleural effusion. Thoracentesis revealed hemothorax and subsequently the patient complained of dizziness and went into shock. Chest CT scan revealed a well-defined nodule with a continuous enlarged vessel. Enhanced CT findings suggested a diagnosis of pulmonary arteriovenous fistula projecting into the intrapleural space from the right lower lung. Partial resection of the right lower lung was performed and the histological study confirmed the final diagnosis.
