Significant reduction of the echogenicity of the compressed cavernous hemangioma.
Eleven hyperreflective hepatic nodules in eight patients were examined by means of intraoperative ultrasonography (US) with the transducer placed on the liver surface. The nodules included four cavernous hemangiomas, four hepatocellular carcinomas, one metastatic tumor, and two regenerative nodules in cirrhotic livers. When the relevant part of the liver was compressed during US observation, the echogenicity was reduced only in the case of cavernous hemangioma. This phenomenon is considered to be unique to cavernous hemangioma.
