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 2: Liposarcoma of kidney.Axial post-contrast computed tomography image of 67-year-old male with surgically proven liposarcoma of kidney shows non-specific contrast enhancement and well circumscribed mass in upper pole of left kidney (arrow) with no associated macroscopic fat.

Mentions: Liposarcomas are classified into five histological subtypes, including well-differentiated, dedifferentiated, myxoid, round cell, and pleomorphic. The histological grade is the most important prognostic factor (7). The most important clinical entity in the differential diagnosis is macroscopic fat-containing angiomyolipoma. However, it may be difficult to make a confident imaging diagnosis of any kind of lipomatous tumor when the lesion does not contain macroscopic fat, as in the case presented in Figure 2.
