Hepatic cavernous hemangioma. CT findings and pathological basis.

CT findings in 113 cases of hepatic hemangioma confirmed pathologically including 52 resected specimens and 8 autopsies were studied in correlation with the typical CT scan of 506 cases of the same disease. Mottling enhancement in the surrounding hepatic parenchyma of hemangioma which never appeared in other kinds of tumor was considered as a pathognomonic sign for diagnosis. It was correlated with the presence of dilated vascular spaces or sinusoids communicating with the tumor itself in the surrounding tissue. The thick wall and thin wall types of hemangioma were discussed.
