Sonographic Evaluation of Clear Cell Renal Cell Carcinoma

Clear cell renal cell carcinoma (RCC) is proposed to arise from the proximal convoluted tubules within the kidney. Diagnostic imaging plays a role in the detection of RCC. A case is presented of a clear cell RCC that was initially identified sonographically. Sonography detected and characterized the mass, which was further evaluated with computed tomography (CT) to obtain additional information, prior to a radical nephrectomy. The use of both CT and sonography led to proper diagnosis and treatment of this suspected tumor
