Radiological findings of 4 cases of infantile hemangioendothelioma of the liver(IHL) were reviewed, which were surgically proven or diagnosed by the clinical findings and sonographic, CT and angiographic findings. Clinical tirads of IHL are abdominal mass (hepatomegaly), congestive heart failure and cutaneous hemangioma. Characteristically, patients of IHL are under 6 months of age and have frequently multifocal lesions which regress spontaneously. Sonographic findings were multifocal well defined discrete masses. Echogenicity was variable, hypoechoic or hyperechoic with or without centrat target. CT was performed in 2 cases and showed multiple centripetally enhancing masses and so it could be diagnosed as IHL, and after that it was cnfirmed by angiography. CT of the other exophytic mass showed inhomogenous enhancing pattern, and diagosed as hepatoblastoma initially.
