Colour-Doppler features of hepatic involvement in Rendu-Osler-Weber disease.

A 39-year-old woman with a past history of Rendu-Osler-Weber disease of 16 years was referred to our unit to evaluate hepatic involvement. Previous pulmonary arteriovenous malformations were treated with embolization. It is known that recurrence of pulmonary arteriovenous malformations (VMs) requires a new treatment modality. On physical examination no skin lesions were found. Laboratory parameters were normal. Ultrasound imaging findings were: Dilation of hepatic artery (diameter 12 mm), tortuous intrahepatic structures, tubular parallel structures to the portal branches and a shunt between hepatic artery and left portal vein. Spleen size was normal (Figs. 1-3).
