Infantile hemangioendothelioma of the liver

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, computed tomographic and angiographic findings. Clinical tirades 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 central 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 confirmed by angiography. CT of the other exophytic mass showed inhomogenous enhancing pattern, and diagnosed as hepatoblastoma initially
