pulmonary arteriovenous malformation: a rare cause of hemoptysis

Pulmonary arteriovenous malformation (PAVM) is a rare cause of hemoptysis and exertional dyspnea. Hereditary hemorrhagic telangiectasia is the most common cause of PAVM, but it can also occur in a variety of acquired medical conditions such as postthoracic trauma, cirrhosis of the liver, and conditions causing chronic pulmonary hypertension. We present a case of PAVM with classical cherry aneurysm of right hilar vessels on routine chest X-ray, which led to further evaluation and successful treatment of PAVM by the transseptal closure of the fistula.
