Hepatic metastases of soft tissue XXXX : CT and MR imaging findings.

@entity1 @entity548 @entity96 @entity5 @entity5426 @entity409 @entity2287
BACKGROUND: We describe the computed tomographic (CT) and magnetic resonance imaging (MRI) findings of hepatic metastases caused by soft tissue @entity5426 to clarify the relation between radiologic appearances and clinicopathologic features. METHODS: CT and MR examinations of 13 @entity1 with hepatic metastases of soft tissue @entity5426 were retrospectively analyzed. RESULTS: Contrast-enhanced CT images showed multiple hypoattenuating lesions relative to the adjacent @entity409 . Lesions contained peripheral areas of enhancement in eight @entity1 (62%). @entity5 showed cystic attenuation with fluid-fluid levels, which were suggestive of @entity548 in five @entity1 (38%). In one @entity1 (8%) with cystic attenuation and fluid-fluid levels, lesions also contained marked enhanced nodular portions located centrally or peripherally. On T1-weighted MR images, all four @entity96 appeared heterogeneous and hypointense relative to adjacent @entity409 . Fluid-fluid levels were identified on T2-weighted MR images in five @entity1 (38%). After an intravenous bolus of @entity2287 -based contrast material was administered, slight peripheral enhancement was seen in three @entity1 (75%). CONCLUSION: The common CT findings of @entity5426 in our series were multiple hypoattenuating lesions often associated with nodular enhancement and cystic lesions with hemorrhagic change.
