儿童神经母细胞瘤的CT表现

CT features of neuroblastoma in childhood

目的:描述儿童神经母细胞瘤的CT表现,以提高对本病的认识。方法:回顾性分析13例经病理证实的神经母细胞瘤的CT表现,研究肿瘤的CT特征。结果:13例中,原发在头部1例,颈部1例,纵隔3例,腹部6例(源于肾上腺4例,源于腹膜后交感神经链2例),盆腔2例。肿瘤形态,其中不规则形2例,圆或椭圆形11例。8例显示钙化,钙化呈散在或弥漫分布斑点样钙化6例,索条状1例,不规则形钙化1例。共10例进行CT增强,增强后均匀强化1例,不均匀强化9例。与血管、气管关系,包绕周围血管4例,推移血管2例,推移气管1例。结论:神经母细胞的CT表现有一定特征,可有助于临床诊断。

Objective：To evaluate CT in the diagnosis of neuroblastoma in childhood. Methods： 13 cases histologically proved, including nettroblastoma 11 cases, ganglionettroblastoma 2 cases were performed on CT. The site, morphology, CT features of the lesions were analyzed retrospectively. Results： The neuroblastoma was found in the head（ 1 ）, neck （ 1 ）, thorax （ 3 ）, abdomen （ 6 ）, including 4cases from adrenal gland, 2 cases from retroperitoneal sympathetic chain and pelvis sympathetic chain （2）. Of 13cases of nettroblastoma, CT showed irregular mass in 2 cases, round or ovary mass in 11 cases, Tumorous calcifications are discrete, diffuse and spotty in 6 cases, striped in 1 case, irregular in 1 case. Enhenced CT demonstrated 1 case homogenous enhencement and 9 cases heterogeneous enhencement of the tumor. CT show vascular encasement in 4cases, vascular compression in 2 cases and tracheal compression in I case. Conclusion：The CT is very helpful in evaluating and instructing chnical diagnosis.
