A 61-year-old woman was admitted to our hospital with one month history of fever. About 15cm in diameter mass was palpated in her right lower abdomen. Plain abdominal roentgenography, ultrasonography and computed tomography showed marked calcification in the cephalic portion of the right kidney, tumors surrounding right kidney and another tumor in the right lower abdomen. All these tumors and the kidney constituted a big mass continuously, and no fatty component was demonstrated. Total excision of the mass including the kidney was performed. The mass was 30×24×10cm in size and 3,240g in weight. Histologically, the tumor was compatible to renal angiomyolipoma. But, radio-opaque shadows which looked like calcification were disclosed to be bones, and fatty tissues were not seen so much. Therefore, the name “benign mesenchymoma” was thought to be more approvable than angiomyolipoma in this case.
Preoperative diagnosis of renal angiomyolipoma is the demonstration of fatty densities in the tumor, and the characteristic extrarenal developrnent should also be taken into consideration. Furthermore, the bone formation of angiomyolipoma, which is very rare might be an important finding to angiomyolipoma.
