Ultrasound-guided percutaneous aspiration of renal angiomyolipoma. Report of two cases diagnosed by cytology.
Two cases are reported in which the diagnosis of renal angiomyolipoma was made by ultrasonically guided aspiration cytology. Vessels, smooth muscle cells and fat were evident in the aspiration smears, in which no epithelial cells were found. Since the treatment of renal angiomyolipoma differs from that of adenocarcinoma of the kidney, the preoperative cytologic diagnosis is of great value.
