Multilocular renal cyst having a distinctive gross feature of multiple, variable sized, noncommunicating cysts is uncommon and uncertain natured lesion. As a treatment modality of multilocular renal cyst, local excision or partial nephrectomy could be done. However, simple or radical nephrectomy might have been performed because of the documented association with malignancy such as Wilms tumor. Herein, we report a case of multilocular renal cyst in an 11-month old infant treated by radical nephrectomy with possibility of combined malignancy.
