【摘要】：【目的】探讨多排螺旋CT(MDCT)在儿童骶尾部肿瘤(SCT)的应用价值,以期提高对儿童SCT的诊断能力。【方法】纳入经穿刺活检或手术病理证实的54例儿童SCT(男22例,女32例,年龄1 d至16岁),所有病例术前均行64排螺旋CT平扫及单期增强扫描。回顾性分析患儿的CT特点及临床资料。【结果】儿童SCT好发于4岁以下儿童,女性多见,其中生殖细胞肿瘤最常见,其次为神经源性肿瘤。54例儿童SCT中,恶性39例,良性15例。在CT检查中,以实性成分为主的肿瘤37例(68%),31例为恶性肿瘤。以囊性成分为主的肿瘤8例(15%),均为良性肿瘤。囊实性或实性肿块伴有明显坏死的肿瘤9例(17%),8例为恶性肿瘤。【结论】儿童恶性SCT发病率高于良性,大部分恶性SCT以实性成分为主、囊实性或实性肿块中伴有明显坏死,而大部分的良性肿瘤以囊性成分为主;大多数SCT在结合CT表现及患儿临床资料的基础上于术前可做出明确诊断。
[Abstract]:[objective] to evaluate the value of multislice spiral CTD SCT in the diagnosis of sacrococcygeal tumors in children. [methods] 54 children with SCT confirmed by biopsy or pathology were included in this study. Age from 1 day to 16 years old, all patients underwent 64-slice spiral CT plain scan and single-phase enhanced CT scan before operation. Ct features and clinical data of children were analyzed retrospectively. [results] SCT was more common in children under 4 years of age than in females. Among them, germ cell tumor was the most common, followed by neurogenic tumor. In 54 cases of children with SCT, 39 cases were malignant and 15 cases were benign. There were 37 cases of solid tumor, 31 cases of malignant tumor, 8 cases of cystic component, 8 cases of benign tumor, 9 cases of cystic or solid mass with obvious necrosis, 8 cases of malignant tumor. [conclusion]. The incidence of malignant SCT in children was higher than that in benign children. The majority of malignant SCT was composed of solid components with obvious necrosis in cystic or solid masses, while most benign tumors were mainly cystic. Most SCT can make a definite diagnosis before operation on the basis of CT findings and clinical data.
