OBJECTIVE: The purpose of this study was to identify CT characteristics of @entity5606 , a rare, aggressive, malignant @entity5 of unknown origin that occurs mainly in @entity1 and young @entity1 . MATERIALS AND METHODS: CT scans of eight @entity1 (newborn to 13 years old; mode, 4 months old; six @entity1 and two @entity1 ) with histopathologic diagnosis of @entity5606 were evaluated retrospectively by two of the authors, who were not blinded to the diagnosis. All eight CT scans were performed with intravenous and oral contrast, and noncontrast intravenous CT scans were available in four cases. The following CT characteristics were evaluated: location of @entity5 within the kidney; presence of @entity730 , subcapsular @entity1410 , multiple @entity5 lobules, enlarged vessels, @entity1350 , or central @entity5 @entity39 or @entity548 ; visibility of @entity5 margin; distant @entity3 ; and @entity5 size. RESULTS: All eight primary @entity5 (five on the left, one of which had contralateral renal nodules) were central in location and involved the hilum. Calcification outlining the @entity5 lobule was present in two of the four @entity5 on noncontrast CT scans. Subcapsular @entity1410 was seen in five @entity1 . Tumor @entity39 and @entity548 were seen in seven @entity1 . @entity5 were well defined from the renal cortex in four @entity1 . Lobules of @entity5 were seen in seven @entity1 . CONCLUSION: CT findings of @entity730 , subcapsular @entity1410 , and lobular appearance in a large, centrally located, and heterogeneous renal mass in a @entity1 suggest a @entity5606 .
