Renal Cell Carcinoma Masquerading as Angiomyolipoma: Pitfalls of Fat Density on CT Scan

Renal Cell Carcinoma Masquerading as Angiomyolipoma: Pitfalls of Fat Density on CT Scan Angiomyolipoma (AML) is a benign renal lesion with the ‘pathognomic’finding of fat density contained within the tumor, usually identified on CT exam. In rare cases, especially when there is minimal fat density or the presence of calcifications within the mass, tumors may be misdiagnosed as AML and most often represent renal cell carcinoma. We present a case of a 59-year-old man diagnosed with AML who underwent subsequent partial nephrectomy and was found to have a large papillary renal cell carcinoma. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Current Urology Karger

Abstract

Angiomyolipoma (AML) is a benign renal lesion with the ‘pathognomic’finding of fat density contained within the tumor, usually identified on CT exam. In rare cases, especially when there is minimal fat density or the presence of calcifications within the mass, tumors may be misdiagnosed as AML and most often represent renal cell carcinoma. We present a case of a 59-year-old man diagnosed with AML who underwent subsequent partial nephrectomy and was found to have a large papillary renal cell carcinoma.
