An ectopic kidney is defined as an atypically placed kidney, due to improper migration from the fetal pelvis, during embryogenesis. The presented CT scan of 72-year-old male with pain and visible hematuria reveals that the right kidney is located in the pelvis. The ectopic kidney has malrotation with a calcified artery and 2 veins. One draining in the right common iliac vein and the other connected to the left common iliac vein-near the bifurcation of vena cava inferior. Usually, pelvic ectopy is asymptomatic. However, it may lead to elevated blood pressure, increased risk of stone formation, infections, and traumatism, due to the atypical anatomical position. Variations in the anatomy of the kidney and its vascular supply are of clinical importance. It is possible to encounter a radiological, surgical, or cancer case, such as the presented.
异位肾的定义是由于胚胎发育过程中从胎儿盆腔迁移不当而导致位置异常的肾脏。所呈现的一名72岁男性因疼痛和肉眼血尿的CT扫描显示右肾位于盆腔内。该异位肾存在旋转不良，伴有一条钙化动脉和两条静脉。一条静脉汇入右髂总静脉，另一条静脉在靠近下腔静脉分叉处与左髂总静脉相连。通常，盆腔异位是无症状的。然而，由于其非典型的解剖位置，可能会导致血压升高、结石形成风险增加、感染和创伤。肾脏及其血管供应的解剖变异具有临床重要性。有可能遇到像所呈现的这种放射学、外科或癌症病例。
