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.

Malignant neuroendocrine tumor of kidney.Axial post-contrast computed tomography image of 52-year-old male demonstrates contrast-enhanced lesion of left kidney (arrows) that was malignant neuroendocrine tumor. Punctate focus of calcification at medial edge of lesion (arrowhead) is renal stone in adjacent calyx.

Figure 3: Malignant neuroendocrine tumor of kidney.Axial post-contrast computed tomography image of 52-year-old male demonstrates contrast-enhanced lesion of left kidney (arrows) that was malignant neuroendocrine tumor. Punctate focus of calcification at medial edge of lesion (arrowhead) is renal stone in adjacent calyx.

Mentions: Among the most common radiological features of all neuroendocrine tumors is calcification (Fig. 3) (10). Although lesions may be heterogeneous on ultrasound (US) and CT, carcinoids of the kidney have a characteristic tendency to show minimal or poor enhancement on contrast-enhanced CT, corresponding to hypovascular or avascular lesions on renal angiography. Octreotide scanning has been recently proposed as a sensitive imaging modality for diagnosing and evaluating the extent of disease (10).
