| Abstract: | A 69-year-old female was referred to Roswell Park Memorial Institute for management of a right kidney tumor. Her evaluation included excretory urography, ultrasound, computerized axial tomography (CT scan), and selective renal angiography. Fine needle aspiration cytology was felt to be consistent with primary renal cell carcinoma. In spite of the radiological appearance of a benign lesion, a right radical nephrectomy was performed because of the positive cytology on fine needle aspiration. The pathological diagnosis was a solitary multilocular cyst of the kidney. |
