Arteriovenous malformation of the bronchial artery showing endobronchial protrusion.
The bronchoscopic findings of arteriovenous malformation of the bronchial artery are compared with findings on angiography and pathology. A non-pulsatile protrusion with engorged vessels on its glossy and uneven surface was seen at the distal portion of the right anterior segmental bronchus. A bronchial angiogram demonstrated that the protrusion corresponded to the hypervascular area of convoluted vessels. Histologically, a glossy, uneven surface and engorged vessels represented normal mucosa overlaying an extramuscular tortuous artery and proliferation of submucosal tiny vessels, respectively. These bronchoscopic findings were important clues for diagnosis.
