title: [Usefulness of power Doppler ultrasound in a patient with renal cell carcinoma in the wall of a simple renal cyst].
abstract: We present a case of renal cell carcinoma in the wall of a simple renal cyst. A 54-year-old man visited our hospital with a complaint of right back pain. Ultrasound study revealed right hydronephrosis, a ureteral stone, and a 9 x 8 cm renal cyst, with a tumor, 2 cm in diameter, in the cyst wall. Power Doppler Ultrasound and enhanced computed tomography demonstrated hypervascularity of the tumor. Clinically, he was diagnosed as renal cell carcinoma and nephrectomy was performed. Pathological findings of the tumor showed clear cell carcinoma in the wall of a simple renal cyst. Twelve months after the nephrectomy, he was free from recurrence.
