Abstract

Primary renal mucinous cystadenoma is a benign cystic renal lesion reported in fewer than 50 cases in English literature. We present a case of a complex cystic lesion of the left kidney in a 74-year-old gentleman with a significant background of left urolithiasis and hydronephrosis. This lesion showed gradual increase in size over eleven years and resulted in gross hydronephrosis and chronic renal impairment. Latest CT and MR imaging demonstrated a Bosniak 4 cystic mass with enhancing nodules suspicious for malignancy. A radical nephrectomy of the left kidney and histopathological examination demonstrated a benign mucinous cystadenoma.

Intraoperative image from the left radical nephrectomy. Multiloculated cystic mass replacing almost the entire kidney.
