Abstract：
BACKGROUND: Non-puerperal uterine inversion is a rare condition with diagnostic and surgical challenges. Clinically, the inverted uterus appears as a mass protruding from the vagina and is often misdiagnosed as a malignant tumor and surgically removed.
METHODS: An 11-year-old girl was admitted to the emergency room due to spontaneous vaginal mass protrusion. The pudendum examination showed an irregular and dark red neoplasm protruding from the vagina. The final diagnosis was non-puerperal uterine inversion with an endometrial polyp.
CONCLUSIONS: MRI is the key to the diagnosis of uterine inversion. Our review confirmed that the 11-year-old girl was the youngest in the world to suffer from non-puerperal uterine inversion.

摘要：
背景：非产褥期子宫内翻是一种罕见的诊断和手术挑战。临床上,子宫倒置表现为从阴道突出的肿块，常被误诊为恶性肿瘤并通过手术切除。
方法：一名11岁女孩因自发性阴道肿块突出而被送进急诊室。阴部检查显示从阴道突出的不规则和暗红色肿瘤。最终诊断为非产褥期子宫内翻伴子宫内膜息肉。
结论：MRI是诊断子宫内翻的关键。我们的审查证实，这名11岁的女孩是世界上最年轻的非产褥期子宫内翻患者。
