Background: Hepatic involvement in hereditary haemorrhagic telangiecta
sia (HHT) consisting of fibrosis, telangiectases, and cirrhosis, has b
een reported as a relatively frequent finding. Case: A 50-year-old man
with HHT presented with monstrous ascites. Liver biopsy demonstrated
multiple dilated sinusoids but not cirrhosis. There were no findings i
ndicative of portal hypertension or malignant disease. Portal pressure
, recorded in hepatic vein wedge position, was normal. Arteriography s
howed numerous hypervascular lesions throughout the liver. The clinica
l course has been stable for more than 2 years. Conclusion: No other r
eason for the monstrous ascites could be found. We thus hypothesize th
at this case of monstrous ascites is due to hepatic involvement in HHT
, presenting as numerous vascular lesions throughout the liver.
