摘要:
【摘要】 目的 探讨肠道脂肪瘤继发肠套叠的多层螺旋CT表现特征及诊断价值。 方法 回顾性分析18例经临床病理证实的肠道脂肪瘤继发肠套叠患者的多层螺旋CT(MSCT)影像及临床资料,将其分为大肠组(7例)与小肠组(11例),总结分析肿瘤的部位、形态、大小、密度及套叠的长度等特征。结果 12例肿瘤呈类圆形,5例呈分叶状,1例呈柱形。10例呈均匀脂肪密度,8例密度不均匀。小肠组11例,包括空肠6例,回肠5例;大肠组7例,包括盲肠2例,升结肠3例,横结肠1例,降结肠1例。大肠组与小肠组脂肪瘤继发肠套叠在瘤体最大径、体积、套叠长度上差异有统计学意义(P<0.05),CT值差异无统计学意义(P>0.05)。 结论 多层螺旋CT能清楚显示肠道脂肪瘤继发肠套叠部位、形态、大小、密度,小肠脂肪瘤继发肠套叠较大肠,瘤体体积小、套叠长。多平面重组和曲面重组可以显示肠套叠的全程,为临床诊疗提供合理依据。

Abstract:
【Abstract】 Objective To explore the multi-slice spiral CT manifestations of intussusception secondary to intestinal lipoma, and to clarify its CT image characteristics and diagnostic value. Methods MSCT images and clinical data of 18 patients with intestinal lipoma secondary intussusception confirmed by clinicopathology were retrospectively analyzed. The tumor was divided into large intestine group (7 cases) and small intestine group (11 cases). The location, shape, size, density and the length of intussusception were analyzed. Results The tumors were round in 12 cases, lobulated in 5 cases and columnar in 1 case. The density was uniform fat densityin 10 cases and uneven in 8 cases. There were 11 cases in small intestine group, including 6 jejunum and 5 ileum; 7 in large intestine group, including 2 cecum, 3 ascending colon, 1 transverse colon and 1 descending colon. There were significant differences in the maximum diameter, volume and length of intussusception between the large intestine group and the small intestine group (P<0.05), but no significant differences in CT value (P>0.05). Conclusion Multi slice spiral CT can clearly show the location, shape, size and density of intussusception secondary to intestinal lipoma. Multi plane reconstruction and curved surface reconstruction can show the whole process of intussusception and provide a reasonable basis for clinical diagnosis and treatment.
