Eleven patients with sharply circumscribed round to ovoid renal cysts measuring 70-90 H on CT are reported. The cysts were hyperdense on unenhanced scans, measuring 30-60 H greater than the adjacent parenchyma, and either hypodense, isodense, or hyperdense on enhanced scans.

Renal cysts are commonly encountered lesions in daily radiological practice. Usually these are simple benign cysts, but they can become complicated in case of hemorrhage, infection and ischemia. When this occurs it can be difficult to differentiate these complicated cysts from cystic renal cell carcinomas (10% of all renal cell carcinomas)

Kidney cysts can be associated with serious disorders that may impair kidney function. But more commonly, kidney cysts are a type called simple kidney cysts — noncancerous cysts that rarely cause complications. Pearlstein AE.
