小肠脂肪瘤的CT诊断

CT diagnosis of small intestinal lipoma

目的:分析小肠脂肪瘤的CT表现,评价其在小肠脂肪瘤诊断中的价值。方法:经手术病理证实的小肠脂肪瘤10例,回顾分析其CT表现。结果:10例患者,手术切除11个肿瘤。发生于十二指肠者3例;空肠2例;回肠5例。肿瘤多呈圆形或类圆形,其中2例带蒂。肿瘤最小者2cm×1cm×1cm,最大者6.2cm×4.2cm×3cm,平均大小3.8cm×2.9cm×2.1cm。CT显示肠腔内边缘规则的圆形或卵圆形低密度肿块,CT值-50～-120HU不等。结论:多层螺旋CT是诊断小肠脂肪瘤有效和可靠的影像学检查方法。

Objective：To analyze the CT features of small intestinal, lipomas. To evaluate the diagnostic value of CT of small intestinal lipomas. Methods：We presented 10 cases of small intestinal lipoma confinned histopathologically after operation. CT features were retrospectively analyzed. Results： Of the 10 patients, one had two small intestinal lesions, for a total of 11 lesions. Three of the 11 tumors occurred in the duodenum, two occurred in the jejunum, and five occurred in the ileum. The tumors were round or oval and two were pedicled in shape. The smallest one was 2cm × 1 cm × 1 cm in size, while the largest one was 6.2cm ×4.2cm × 3cm （mean, 3.8cm × 2.9cm × 2. 1cm）. Conclusion： Multi-sllce spiral CT is efficient and reliable imaging method for diagnosis of small intestinal lipomas.
