We present the case of a patient in whom a horseshoe kidney was discovered during US examination performed for abdominal pain. MRI confirmed this finding and also revealed a supernumerary kidney. The three kidneys were fused, with the supernumerary kidney forming the isthmus of the horseshoe kidney. Whereas horseshoe kidney is a relatively common renal malformation, a supernumerary kidney is one of the rarest renal malformations. The coexistence of these two malformations and especially the particular disposition of the supernumerary kidney is very rare. Knowledge of this malformation is interesting because it can lead to complications such as lithiasis, hydronephrosis, infections, and neoplasms and because it has important implications for surgical planning.
我们报告一例患者，其因腹痛接受超声检查时发现马蹄肾。磁共振成像（MRI）证实了这一发现，还显示存在一个额外肾。这三个肾脏融合在一起，额外肾构成了马蹄肾的峡部。马蹄肾是一种相对常见的肾脏畸形，而额外肾是最罕见的肾脏畸形之一。这两种畸形并存，尤其是额外肾的特殊位置非常罕见。了解这种畸形很有意义，因为它可能导致诸如结石、肾积水、感染和肿瘤等并发症，并且对手术规划有重要影响。
