Bladder duplication is an extremely rare congenital anomaly of the urinary system that is more frequent in boys; the literature is limited to case reports and case series. We describe two cases of bladder duplication in two infant girls with an uncommon variant of complete sagittal septum not included in the Abrahamson classification. The diagnosis was made using magnetic resonance urography, combining excellent anatomical information and static and dynamic evaluation of the urinary tract. The diagnostic information provided by MR-urography was confirmed on surgical exploration. These cases provide an opportunity for paediatric radiologists and urologists to learn more about bladder duplication and improve their diagnosis of this rare condition.
膀胱重复畸形是一种极为罕见的泌尿系统先天性异常，多见于男孩；文献报道仅限于病例报告和病例系列。我们描述了两名女婴膀胱重复畸形的病例，其属于 Abrahamson 分类中未包括的不完全矢状隔罕见变异型。采用磁共振尿路成像（MRU）进行诊断，这种方法结合了优秀的解剖学信息以及对尿路的静态和动态评估。MRU 提供的诊断信息在手术探查中得到了证实。这些病例为儿科放射科医生和泌尿科医生提供了更多了解膀胱重复畸形的机会，并有助于提高对这种罕见疾病的诊断水平。
