DAHİLİ BİLİMLER / MEDICAL SCIENCES Olgu Sunumu / Case ReportsOur aim was to present a case of incidentally detected pelvic pancake kidney anomaly with imaging findings in a 65-years-old male patient and to discuss its clinical significance. Pancake kidney, also called pelvic fused kidney, lump or cake kidney, is a rare type of congenital renal fusion anomaly. It is characterized by the presence of a lobulated pelvic renal mass which has a dual parenchymatous system without an intervening septum. Radiologic and scintigraphic findings of the patient having symptoms of urgency were consistent with a pelvic pancake kidney. Although urinary system anomalies often coexist with malformations of other organs and systems, no associated anomalies could be detected in our case.
