Two sets of US images of confirmed 27 hepatic hemangiomas in 20 cases were compaired. In one set, patients were treated by applying artificial pressure to the liver; in the other set, patients were treated without applying that pressure. Pressure was applied by (a) deep inhalation, (b) manual compression of the abdominal wall, or (c) a combination of both (a) and (b). Nine out of 17 hyperechoic hemangiomas, and two out of eight mixed-echo hemangiomas showed change in the echogenicity, while none of the two simply hypoechoic ones yielded no change in the echogenicity. The overall sensitivity was 41%. Even nodules smaller than 30 mm in diameter yielded change in echogenicity in 40%. This phenomenon, is thought to be specific to hemangioma as the authors had previously reported in the field of intraoperative sonography. The observation of this change in echogenicity is a good confirmatory method in the diagnosis of hepatic hemangiomas by routine ultrasonography.
