A case of pulmonary arteriovenous malformation in the setting of Rendu Osler Weber syndrome.

Rendu Osler Weber syndrome is a rare disorder, in which arteriovenous malformations are a hallmark feature. We describe the case of a 77-year-old female patient who presented with dyspnea, recurrent epistaxis, and signs of right ventricular heart failure, along with hypoxia and severe anemia. Several imaging modalities facilitated diagnostic workup. The computed tomography revealed an area of pulmonary arteriovenous malformation. Visceral involvement, along with clinical criteria and medical history, established the diagnosis of Rendu Osler Weber syndrome. The patient was scheduled for embolization of the PAVM soon after the diagnosis. Proper imaging, guided by clinical suspicion can be extremely helpful in diagnosing and treating this rare entity.
