A 63-year-old female presented with shortness of breath. Thoracoabdominal computed tomography (CT) angiography demonstrated multiple pulmonary and hepatic arteriovenous malformations (Fig. 1). Rendu-Osler-Weber disease is characterized by multiple mucocutaneous telangiectasias and visceral arteriovenous malformations.
Osler-Weber-Rendu is an autosomal dominant disease. It is characterized by multiple mucocutaneous telangiectasias, recurrent epistaxis, and visceral arteriovenous malformations. Vascular structures of the lung and gastrointestinal tract frequently involve.1 With the advent of multidetector CT, hepatic and pulmonary involvement with Rendu-Osler-Weber is commonly recognized.1
In liver involvement of Rendu-Osler-Weber disease, there is shunting from the hepatic artery to the portal or hepatic veins.2 These vascular anastomoses can diagnosed by CT or catheter angiography. Transcatheter embolization of hepatic or pulmonary arteries can perform in lung or liver involvement of patients with Rendu-Osler-Weber disease. Transplantation can perform in patients with liver or pulmonary insufficiency.3
