摘　　要：目的:评价儿童神经母细胞瘤的CT检查价值。方法:回顾性分析24例手术病理证实神经母细胞瘤患者的临床资料,分析肿瘤的CT直接征象和间接征象。结果:神经母细胞瘤起源于肾上腺19例,腹部交感神经链3例,后纵隔交感神经链2例。CT特点:肿瘤呈类圆形或不规则形软组织密度肿块,部分跨中线生长,多数肿瘤体积较大,肿瘤密度多不均匀,可见斑片状低密度坏死区及斑块、沙砾状高密度钙化影;肿瘤易侵犯邻近结构,可包埋大血管,淋巴结转移多见,可见骨转移及硬脑膜转移,可见主动脉壁密度明显高于其内血液。化疗后肿瘤有不同程度缩小,其内钙化影浓聚并增大。结论:CT在儿童神经母细胞瘤治疗前的诊断、治疗方法的选择及治疗后随访均有重要价值。Objective To investigate the value of CT to the examination of pediatric neuroblastoma.Methods The clinical data,especially the direct and indirect CT signs of neuroblastomas in 24 cases were retrospectively analyzed.Results Nineteen tumors originated from adrenal gland,3 tumors from the sympathetic nerve chain of abdomen and 2 tumors from the sympathetic nerve chain of posterior mediastinum.CT showed the tumors round or erose.The density of tumors was similar to the soft tissue and inhomogeneous,in which scrap necrosis and gravel-shaped calcification were seen.Some tumors exceeded median line.Most tumors were large in size.The tumor invaded near tissue and encased blood vessels.Metastasis in lymph nodes was more and some cases had metastasis in bone and endocranium.The density of aortic wall was higher than blood.After chemotherapy,the size of tumor shrank and calcification was enlarged.Conclusion CT has a very important value to the diagnosis,therapy and follow-up.
