A 63-year-old female with Rendu-Osler-Weber disease had general fatigue and right hemiparesis. A computed tomography (CT) scan of her head demonstrated an enhancing cystic mass in the left frontal lobe, and it was diagnosed as a brain abscess and then drainaged. Thereafter, a pulmonary arteriovenous malformation (PAVM) identified in the left lingular segment by chest CT scan and the PAVM was resected by partial resection of the lung.
