Curious manifestations in cavernous hemangioma of the liver.
We report a cavernous hemangioma of the liver with some curious findings. Angiography showed a hypervascular lesion and the arterioportal shunt which commonly is regarded as a pathognomonic sign of malignancy. Laparoscopy showed a well-defined, reddish-purple elevated lesion with a central umbilication. As the patient was a painter and dealing with vinyl chloride monomer, we suspected the possibility of hemangiosarcoma. The lesion proved to be a cavernous hemangioma with central fibrous replacement probably in consequence of thrombosis of some cavernous spaces.
