title: Hyperdense renal cysts.
abstract: Three cases of surgically proven benign renal cysts are presented that demonstrated high density on computed tomography. The lesions shared the common characteristics of hyperdensity, nonenhancement with intravenous contrast material, round shape, and sharp margination. It is suggested that these criteria may indicate that such lesions are potentially benign, which may prompt a more conservative surgical approach.
