Pulmonary arteriovenous malformation in Osler-Weber-Rendu syndrome

摘要

Osler-Weber-Rendu syndrome, also known as hereditary hemorrhagic telangiectasia, is an autosomal dominant disorder typically identified by the triad of telangiectasia, recurrent epistaxis, and a positive family history of the disorder. A 45-year-old man presented with/ recurrent epistaxis and gastrointestinal bleeding. Chest computed tomography (Figure 1) and multidetector computed tomography angiography (Figure 2) confirmed a right pulmonary arteriovenous malformation. The patient was successfully treated by a right middle lobectomy.
