Ewing sarcoma, including classical Ewing sarcoma of the bone and primitive neuroectodermal tumors arising in bone or extraosseous primary sites, is a highly aggressive childhood neoplasm. We present two cases of Ewing sarcoma arising from the vagina in young girls. Previously reported cases in literature focused on their pathologic rather than radiographic features. We describe the spectrum of multimodality imaging appearances of Ewing sarcoma at this unusual primary site. Awareness of vaginal Ewing tumors may facilitate prompt diagnosis and lead to a different surgical approach than the more commonly encountered vaginal rhabdomyosarcoma.
尤因肉瘤，包括骨的经典尤因肉瘤以及发生于骨或骨外原发部位的原始神经外胚层肿瘤，是一种侵袭性很强的儿童肿瘤。我们报告两例发生于年轻女孩阴道的尤因肉瘤。文献中先前报道的病例侧重于其病理特征而非影像学特征。我们描述了尤因肉瘤在这个不寻常的原发部位的多模态影像学表现。认识阴道尤因肿瘤可能有助于早期诊断，并导致与更常见的阴道横纹肌肉瘤不同的手术方法。
