population aged > 50 years have renal cysts [5]. Most cysts are benign and asymptomatic. A palpable mass, pain from haemorrhage into the cyst, obstructive symptoms and infections are rare presentations. A simple cyst is a fluid-filled, non-neoplastic lesion; most are unilocular, contain straw-coloured fluid, arise from the cortex and are smooth-walled. On CT they are sharply marginated, round, smooth, homogenous and thin-walled, and have attenuation values of 10 to 20 Hounsfield Units (HU), with no enhancement on administration of intravenous contrast medium.
