Localized cystic disease of the kidney: a rare entity.

Localized cystic disease of the kidney is a benign nonsurgical entity and presents with multiple cystic lesions in just one portion of the kidney or involves the entire one kidney. We report a case of localized cystic disease of the kidney in a 16 year-old-male. This patient underwent an ultrasound examination and incidentally found to have multiple cysts in the right kidney whereas the left kidney was normal. Diagnosis was confirmed by typical MRI findings, absence of any family history, normal results of urine analysis and renal function tests.
