“…The most probable cause of crossed renal ectopy was abnormal development of the ureteric bud during the fourth to eighth weeks of gestation. 5 In 90% of patients, the crossed kidney was fused with the normal kidney. Crossed renal ectopy anomaly is two times more common in males and the cross from left to right was more common than the cross from right to left.…”

Crossed renal ectopy (CRE) is the second most common fusion anomaly of the kidney, with an incidence of 1 in 7000 autopsies; it comes in second after horseshoe kidney. Crossed renal ectopy is associated with an ectopic ureter and generally an ectopic kidney fused with a normal kidney. A 7-month-old boy who had left-toright crossed non-fused renal ectopy and multicystic renal dysplasia with ureterocele in nonectopic kidney was reported in English language literature. In this article, we present the first case of CRE where surgical intervention has been performed.

“…Crossed renal ectopia is seen in 1:7000 and often incidentally detected. It can be fused in 85% where the ectopic kidney fuses with the orthotopic kidneys [9,26] . Commonest fusion pattern is fusion of lower pole of orthotopic kidney to the upper pole of crossed ectopic kidney.…”

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.

“…Most cases are diagnosed incidentally since they are often asymptomatic. Flank or abdominal pain, abdominal mass, hematuria, dysuria, urinary tract infections, renal failure, fever and hypertension are the most common clinical manifestations as previously reported [4] . In our case, however, the female patient had chyluria.…”
