小儿头颈部横纹肌肉瘤的影像学诊断

Imaging Diagnosis of Head and Neck Rhabdomyosarcomas in Children

目的:探讨小儿头颈部原发性横纹肌肉瘤的影像学特征。材料和方法:对19例经手术病理证实的头颈部横纹肌肉瘤的影像学及临床特征进行回顾性分析。结果:病灶表现为软组织肿块,B超上为实性或混杂团块,CT或MRI上增强前较均匀,增强后中度不均匀强化,放射性核素扫描可以发现骨侵犯或转移。结论:头颈部横纹肌肉瘤影像学具软组织肿瘤的一般特点,无明显特异性,确诊需依靠病理诊断。

Purpose： To explore the imaging features of head and neck primary rhabdomyosarcoma in children, Materials and Methods： The imaging features and clinical characteristics of 19 pediatric patients with head and neck rhabdomyosarcoma were retrospectively analyzed, Results： The lesion of the tumor was composed of soft tissue, solid or mixed mass in ultrasonogram, homogeneous mass in unen-hanced CT or MRI, and moderately enhancement in contrast-enhanced CT or MRI. The isotope scanning helped to find bone invasion or metastases.Conclusion： The imaging features of the head and neck rhabdomyosarcoma were the same as that in other sites and unspecific. A pathologic diagnosis was needed.
