Pancake kidney in a geriatric patient: radiologic and scintigraphic findings

Altmışbeş yaşındaki erkek olguda insidental olarak saptanan pankek böbrek anomalisini görüntüleme bulguları ile sunmayı ve klinik önemini tartışmayı amaçladık. Pelvik füzyon anomalisi gösteren böbrek veya kek böbrek olarak da adlandırılan ‘pankek böbrek’ nadir görülen bir konjenital renal füzyon anomalisidir. Arada septum olmaksızın dual parankim sistemine sahip lobüle konturlu, pelvik yerleşimli renal kitle olarak karakterizedir. Ani idrar yapma isteği ve idrara sıkışma yakınmaları olan hastanın radyolojik ve sintigrafik bulguları pelvik pankek böbrek ile uyumlu bulundu. Üriner sistem anomalileri sıklıkla diğer organ ve sistem malformasyonlarıyla birliktelik göstermesine rağmen, olgumuzda eşlik eden başka anomali saptanamadı.

Geriatrik olguda pankek böbrek: Radyolojik ve sintigrafik bulgular

Our 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.
