“…On USG, clue to diagnosis is poor visualization of bilateral lower pole which should alert the sonographer to look for abnormal tissue anterior to aorta representing the isthmus. Lack of awareness could lead to overlooking the diagnosis with underestimation of renal length or mistaking the preaortic tissue for mass or lymphnode [17,29,30] . CT and MRI help in delineating the details of collecting system and arterial anatomy, differentiating functioning isthmus from fibrous tissue and for early detection of complications ( Figures 13 and 14).…”

Congenital abnormalities of the kidney and urinary tract (CAKUT) include a wide range of abnormalities ranging from asymptomatic ectopic kidneys to life threatening renal agenesis (bilateral). Many of them are detected in the antenatal or immediate postnatal with a significant proportion identified in the adult population with varying degree of severity. CAKUT can be classified on embryological basis in to abnormalities in the renal parenchymal development, aberrant embryonic migration and abnormalities of the collecting system. Renal parenchymal abnormalities include multi cystic dysplastic kidneys, renal hypoplasia, number (agenesis or supernumerary), shape and cystic renal diseases. Aberrant embryonic migration encompasses abnormal location and fusion anomalies. Collecting system abnormalities include duplex kidneys and Pelvi ureteric junction obstruction. Ultrasonography (US) is typically the first imaging performed as it is easily available, noninvasive and radiation free used both antenatally and postnatally. Computed tomography (CT) and magnetic resonance imaging (MRI) are useful to confirm the ultrasound detected abnormality, detection of complex malformations, demonstration of collecting system and vascular anatomy and more importantly for early detection of complications like renal calculi, infection and malignancies. As CAKUT are one of the leading causes of end stage renal disease, it is important for the radiologists to be familiar with the varying imaging appearances of CAKUT on US, CT and MRI, thereby helping in prompt diagnosis and optimal management.

“…If a pancake kidney has to undergo surgery, division of the parenchyme presents potential problems such as renal vascular damage, postoperative renal failure and eventual renal failure (14). On the other hand, the isthmus connecting the inferior poles of horseshoe kidney can be safely divided to facilitate surgical conditions such as underlying aortic aneurysms (15).…”

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.

“…The two ureters empty normally into the bladder, arising from the anterior surface of the disk-like kidney. 4 Many cases are asymptomatic, although there is an increased incidence of recurrent urinary tract infection. In adults it has been mentioned as an incidental finding in patients who have undergone abdominal aortic aneurysm repair.…”

“…In adults it has been mentioned as an incidental finding in patients who have undergone abdominal aortic aneurysm repair. 4 In childhood, pancake kidney has been described in syndromes with an increased incidence of renal fusion anomalies such as Klippel-Feil syndrome. 5 Terminal ventricle of the conus medullaris is a cystic dilatation of the spinal cord central canal ependymal-lined.…”
