摘要：Background and Objective : Horseshoe kidney is the most common renal fusion anomaly with a reported prevalence of 1 in 400 persons with a male to female ratio of 2:1. In many cases its presence may go unnoticed and undiagnosed because the patient may remain asymptomatic throughout life. The objective of our study is to report radiological and anatomical features of horseshoe kidney detected incidentally during retrospective evaluation of multidetector computed tomography scans. Materials and Methods : Contrast enhanced multidetector computed tomography scans of 682 patients, 355 males and 327 females, were reviewed retrospectively. Results: Seven cases of horseshoe kidney were detected incidentally, six males and one female, with an incidence of 1.02 %. In all cases, malrotation of the kidneys were observed with the hilum facing anteriorly or anterolaterally. The isthmus was made up of parenchymal tissue in all the cases and the fusion was midline in four cases and lateral in three cases. Horseshoe kidney in all cases was supplied by multiple renal arteries, varying from 3 to 6. In three cases symmetrical arterial supply and in the rest asymmetrical supply was observed. Nephrolithiasis and hydronephrosis were noted in two patients. No other associated congenital anomaly was observed in all seven patients. Conclusion: Contrast enhanced multidetector computed tomography evaluation of patients with horseshoe kidney provide excellent information about its vascularity, collecting system and other associated conditions.
