Hepatic involvement in hereditary hemorrhagic telangiectasia mimicking focal nodular hyperplasia.

ABSTRACT

Accurate diagnosis of hereditary hemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber disease, is important for reducing the risk of complications. Hepatic involvement in HHT is usually asymptomatic, but when present can cause noted morbidity and mortality. A 62-year-old woman presented with moderate upper-abdominal pain and tachycardia. A diagnosis of HHT was made based on the findings of hepatic involvement in a contrast-enhanced abdominal computed tomography (CT) scan, the presence of arteriovenous malformations (AVMs; a.k.a. telangiectasias) on mucocutaneous surfaces, and a history of recurrent epistaxis. Imaging methods are important diagnostic tools in patients suspected of having HHT.
