| ［摘要］ 目的 探讨小儿横纹肌肉瘤（RMS）的CT和磁共振成像（MRI）表现，提高对该病的认识。方法 收集经该院手术及病理证实的19例小儿横纹肌肉瘤，结合相关文献分析其CT和MRI表现。结果 位于头面部者2例，腹腔内2例，盆腔内11例，四肢2例，脊柱旁2例。胚胎型17例，腺泡型2例。RMS影像表现为软组织密度或信号肿块，增强后明显强化，可引起邻近骨质溶骨性破坏。结论 RMS具有软组织恶性肿瘤的一般影像特征，但缺乏特异性，应结合患儿年龄及临床特征作出综合诊断。 |

| Abstract: |
| ［Abstract］ Objective To explore the imaging features of rhabdomyosarcoma in children.Methods Clinical data and imaging findings of 19 children with rhabdomyosarcoma were retrospectively analyzed.Results Two cases were located in head and face，2 in abdominal cavity，11 in pelvic cavity，2 in extremities, and 2 near to vertebral column.Seventeen cases were embryoid rhabdomyosarcoma, and 2 cases were alveolar rhabdomyosarcoma.The imaging findings included similar density or signal intensity to soft tissue,obvious enhancement,and lytic lesion of adjacent bone.Conclusion The imaging features of rhabdomyosarcoma are the same as tumours of soft tissue and unspecific. We can make a correct diagnosis by combining the age of children with clinical features. |
