Thickening of the wall of the bile duct due to intramural collaterals in three patients with portal vein thrombosis.
OBJECTIVE
We report three cases of a rare form of cavernoma developed within the wall of the common bile duct.


CONCLUSIONS
To our knowledge, this kind of portal cavernoma has not been described in the literature. Because the cavernoma may be easily confused with other causes of bile duct wall thickening, color Doppler sonography is mandatory for a correct diagnosis.
