A total of 154 cases of adult patients who had undergone treatments for hepatic cavernous hemangioma (HCH) in the Japanese literature since 1980 including our own two cases was reviewed. The age ranged from 22 to 74 years, with an average of 50.8 in males and 49.1 in females and with a male-to-female ratio of 1 : 1.5. There was no significant difference in average ages between the sexes and the patients in their 40's and 50's constituted the majority of the cases. Palpable abdominal mass and/or hepatomegaly were noted in 36% of the patients, abdominal pain in 32% and coagulopathy in 9%. Twenty-five patients (21%) showed no symptoms. The diagnosis of HCH before treatment was established in 103 patients mainly by utilizing imaging modalities. Selective hepatic angiography and computed tomography with a bolus injection of the contrast material were the usual diagnostic methods. HCH arising from the left lobe was noted in 40% of the patients, from the right lobe in 37% and multiple occurrence was noted in 19%. So-called giant hemangioma with its maximum diameter of 4 cm or more was noted in 113 patients. In HCH having the diameter less than 4 cm, differentiation from hepatocellular carcinoma was most important. The main treatment for HCH was surgical removal. Although extirpation of HCH per se is preferable, segmental or more aggressive hepatectomy was carried out in 92 patients. The extent of liver resection was decided mainly in consideration of the size and the capsule of HCH except for cases suspected of hepatocellular carcinoma. Ligation of the hepatic artery or portal vein was carried out in 13 patients showing unresectable HCH at surgery. Only one patient met operation-related death.
