Hepatic involvement in hereditary hemorrhagic telangiectasia: helical computed tomography features in 24 consecutive patients

Journal of Computer Assisted Tomography

Abstract

Among the various organs that may be affected by hereditary hemorrhagic telangiectasia (HHT), the liver can show various degrees of vascular and parenchymal involvement. The purpose of this prospective study comprising a large series of patients was to reassess the computed tomography (CT) features of hepatic involvement in HHT using helical CT. Twenty-four consecutive patients with HHT had prospective helical CT of the liver, including noncontrast, arterial-dominant, and portal-dominant phases. The CT images were analyzed by 2 readers in consensus to determine the presence of vascular and parenchymal abnormalities. The diameter of the proper hepatic artery in these 24 patients was compared with that in 24 healthy subjects (Student t test). Helical CT was normal in 5 patients (21%) and abnormal in 19 patients (79%). Vascular abnormalities were found in 16 patients (67%), consisting of marked dilatation of the hepatic artery (n = 16), intrahepatic telangiectases (n = 12), arteriovenous shunting (n = 5), and arterioportal shunting (n=3). The diameter of the proper hepatic artery was greater in the patients with HHT than in control subjects (6.12 +/- 2.52 mm vs. 3.29 +/- 0.65 mm, respectively; P < 0.05). Helical CT showed nodular ...Continue Reading

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.
