Bleeding after biopsy of a bronchial artery arteriovenous malformation presenting as an endobronchial mass: Case report and literature review

Bronchial arteriovenous malformation is a rare disease in which there is an abnormal communication between a bronchial artery and pulmonary artery or vein. We present a case of a 73-year-old woman who was referred for further evaluation and management of a right middle lobe endobronchial mass. After biopsy of the lesion, there was significant bleeding that required urgent right middle lobectomy. A bronchial artery arteriovenous malformation was identified during the surgery.
