Unusual Malignant Solid Neoplasms of the Kidney: Cross-Sectional Imaging Findings.

Karaosmano─člu AD, Onur MR, Shirkhoda A, Ozmen M, Hahn PF - Korean J Radiol (2015)

Bottom Line: Malignant kidney neoplasms are the most frequently encountered solid kidney masses.Although renal cell carcinoma is the major renal malignancy, other solid malignant renal masses should be considered in the differential diagnosis of solid renal masses that do not contain a macroscopic fatty component.In this pictorial essay, we present the imaging findings of a primitive neuroectodermal tumor, primary liposarcoma of the kidney, primary neuroendocrine tumor, leiomyosarcoma, synovial sarcoma, malignant fibrous histiocytoma, sclerosing fibrosarcoma and renal metastasis of osteosarcoma.

Mentions: Sclerosing fibrosarcoma of the kidney is a very rare subtype of renal sarcoma. Fibrosarcoma of the kidney usually arises from fibrous and connective tissue of the renal capsule (27). Fibrosarcomas appear as large heterogeneously enhancing soft-tissue masses on CT and MRI (Fig. 7) (13). The prognosis of this tumor is very poor, as the tumor presents with a rapid growth rate and aggressive behavior and the only potentially curative treatment is surgery (13).
