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.

Figure 6: Malignant fibrous histiocytoma of kidney.A. Unenhanced axial computed tomography (CT) image demonstrates well-defined solid mass (arrow) arising from left renal capsule. B. Contrast-enhanced axial CT image reveals heterogeneous enhancement in mass (arrow).

Mentions: Malignant fibrous histiocytoma of the kidney presents as a well-defined soft tissue mass with inhomogeneous minimal enhancement with slightly higher attenuation than the skeletal muscle on contrast-enhanced CT (Fig. 6) (24). Decreased attenuation corresponding to regions of myxomatous tissue, cystic degeneration, hemorrhage, or necrosis is observed on CT.
