摘　　要：目的探讨分析CT影像学特征在鉴别儿童腹膜后节细胞神经母细胞瘤(GNB)与神经母细胞瘤(NB)的临床应用价值。方法回顾性分析我院2022年4月至2023年4月经病理检查确诊的47例GNB患儿和56例NB患儿的临床资料。对两组患儿进行CT扫描鉴别,比较两组CT平扫及增强扫描影像学特征。结果NB患儿肿瘤病灶最大直径高于GNB患儿(P<0.05)。NB患儿肿瘤形态不规则、边界模糊、跨越中线生长、周围血管包埋、瘤周和瘤内血管影像显示、淋巴结转移和浸润及脏器转移比例高于GNB患儿(P<0.05)。结论CT影像学特征可较好地鉴别儿童腹膜后GNB和NB,GNB多呈现为边界清晰且形态规则,与周围血管关系以推移为主,很少发生远端转移,恶性程度较低,而NB则多表现为边界模糊、形态不规则肿块,跨越中线生长,特征为局部浸润、血管包埋、脏器和淋巴结转移,恶性程度较高。Objective To explore and analyze the clinical application value of CT imaging features in differentiating retroperitoneal ganglioneuroblastoma(GNB)and neuroblastoma(NB)in children.Methods The clinical data of 47 GNB children and 56 NB children diagnosed by pathological examination in our hospital from April 2022 to April 2023 were retrospectively analyzed.Both groups received CT scan differentiation,and the imaging features of plain and enhanced CT scans were compared between the two groups.Results The maximum diameter of tumour lesions in the NB children was larger than that in the GNB children(P<0.05).The rates of tumor irregular morphology,blurry boundaries,growth across the midline,surrounding vascular encapsulation,imaging display of peritumoral and intratumoral vessels,lymph node metastasis,infiltration and organ metastasis in the NB children were higher than those in the GNB children(P<0.05).Conclusions CT imaging features can better differentiate retroperitoneal GNB and NB in children.Most GNB tumors have clear boundaries and regular morphology,with predominantly nudging to the surrounding blood vessels,fewer distal metastases and less malignancy,but NB is often characterized by blurred boundaries,irregular morphology,and tumor growth across the midline,local infiltration,vascular embedding,organ and lymph node metastasis,with higher malignancy degree.
