title: Malignant rhabdoid tumor of the liver: a case report with US and CT manifestation.
abstract: A case of malignant rhabdoid tumor (MRT) of the liver in a 4-month-old boy with hepatomegaly was described with the help of US and CT findings. The boy had multiple liver tumors, and the liver parenchyma showed a diffuse heterogeneous appearance. Lymph node swelling was noted, although the alpha-fetoprotein concentration was not elevated. A diagnosis of MRT was confirmed pathologically. Twenty-seven cases of MRT of the liver with solitary tumors, multiple tumors, or diffuse infiltration have been reported in the English-language literature. Diagnostic imaging plays an important role in detecting metastasis because of the high frequency of distant metastasis in MRT of the liver.
