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.

Metastatic osteosarcoma in kidney.Axial post-contrast computed tomography image of 19-year-old boy with metastatic osteosarcoma of lower extremity demonstrates large calcified metastatic deposit in right kidney (black arrow). Note calcified left adrenal (white arrow) and bilateral perinephric space (arrowheads) metastases.

Figure 8: Metastatic osteosarcoma in kidney.Axial post-contrast computed tomography image of 19-year-old boy with metastatic osteosarcoma of lower extremity demonstrates large calcified metastatic deposit in right kidney (black arrow). Note calcified left adrenal (white arrow) and bilateral perinephric space (arrowheads) metastases.

Mentions: Metastatic disease of the kidney is not common and is mostly seen in patients with a neoplasm of the lung, breast, gastrointestinal tract, or melanoma (28). Osteosarcoma of the kidney may be primary or more commonly metastatic. It is often bilateral, as in our case, and clinically silent (29). These lesions may show extensive calcification on radiographs, occasionally in a sunburst pattern, and may even be detectable on plain radiography (Fig. 8). Nuclear medicine scans with technetium-99 may demonstrate diffuse uptake (2). Clinically occult metastatic renal osteosarcoma is not rare and can be seen in 10% of autopsies of patients who die from osteosarcoma (30).
