Hyperdense renal cyst

Hyperdense renal cyst

Archivos Espanoles de Urologia 55(7): 856-858

We update the diagnostic criteria for renal cystic masses, emphasising in the clinical entity known as hyperdense renal cyst. We report the case of a male patient who presented with an atypical left renal cyst. Radiological examinations (US and CT) were performed. A description of renal cyst classification is made. We review the diagnostic criteria for hyperdense renal cyst using the iconography from this case and also its therapeutic approach. An image compatible with left simple renal cyst was found on ultrasound. A CT scan study showed an homogeneous mass with a high attenuation value, non vascular in nature, which complies with all diagnostic criteria for hyperdense renal cyst. Hyperdense renal cyst is a simple cyst which has suffered bleeding or infection. Diagnosis is made by CT scan and it does not require treatment.
