Carcinoma in a Renal Cyst: Computed Tomography Diagnosis

Abstract
A [human] case of carcinoma in a renal cyst diagnosed by computed tomography [CT] is reported. Ultrasound was unavailable because of scheduling difficulties; CT provided a useful alternative in identifying the cystic and solid features of the mass. There was a good correlation of the CT scan with pathology except for a small tumor nodule at the base of the cyst, which was not seen on the scan.
