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。[Objective ] To evaluate the diagnostic values of multi-detector spiral computed tomography （MDCT） in pediatric sa- crococcygeal tumors （SCT） and to improve the diagnostic ability. [ Methods ] 54 children （22 male and 32 female, age between 1 day and 16 years old） with pathologically confirmed SCT were involved in oar study. All of them received 64-row spiral Computed Tomog- raphy before surgery, CT characteristics and clinical data were retrospectively analyzed. [ Results ] Pediatric SCT are more common in female children under four years old, with the germ cell tumors most common, followed by neurogenic tumors. Among the 54 SCT, 39 cases were malignant and 15 were benign （malignant： benign - 2.60： 1）. In CT image findings, 37 cases （68%） were mainly solid mass, with 31 cases confirmed malignant by pathology. 8 cases （15%） were mainly cystic, with all of them confirmed benign by pa- thology. 9 cases （ 17% ） were cystic-solid or with obvious necrosis in solid mass, with 8 cases confirmed malignant by pathology. [ Conclusion] Malignant pediatric SCT are more common than benign SCT. Most malignant SCT are mainly solid mass or cystic-solid or with obvious necrosis in solid mass, and most benign tumors are mainly cystic. Combined with clinical data, MDCT can help to cor- rectly diagnose SCT before surgery.
