目的：探讨磁共振成像（MRI）检查在儿童颈部肿块中的应用价值。方法回顾性分析2006年5月至2013年12月因颈部肿块行MRI检查的140例患儿的临床资料，其中34例行病理检查。结果 MRI诊断140例患儿中，良性肿块103例（73.6%），主要为脉管性畸形62例、血管瘤30例，其余为囊肿、错构瘤、感染性肿块等；恶性肿瘤29例（20.7%），主要为淋巴瘤22例、横纹肌肉瘤3例、朗格罕细胞组织细胞增生症3例、神经母细胞瘤1例；另8例（5.7%）未定性。在103例良性肿块患儿中4例行病理检查，与MRI诊断一致；29例恶性肿瘤患儿中25例行病理或骨髓细胞形态学检查，与MRI诊断一致22例。结论 MRI有助于儿童颈部肿块的诊断，以及治疗方案的选择及随访。%Objectives To evaluate pediatric neck masses with magnetic resonance imaging (MRI). Methods In this retrospective study, 140 children with neck masses underwent MRI were collected from May 2006 to December 2013. Of them 34 cases went through pathological examinations. The results of MRI diagnosis and pathology were compared in 34 cases. Results In 140 children with neck masses diagnosed by MRI, 103 (73.6%) cases were benign lesions, including 62 vascular malformations, 30 hemangiomas, then cysts, hamartoma, infectious lumps etc., 29 (20.7%) were malignant tumors, including 22 lymphomas, 3 rhabdomyosarcomas, 3 Langerhans cell histiocytosis, 1 neuroblastoma, and 8 (5.7%) cases were undeter-mined masses. Four in 103 cases with benign lesions were performed by pathological examination and all had been con-firmed. Tewenty-five in 29 cases with malignant tumors were performed by pathological examination and 22 cases had been confirmed. Conclusion MRI can help to diagnose the pediatric neck masses and to guide the treatment and follow-up.
