摘　　要：目的:探讨原发性肠脂垂炎(PEA)的CT表现及鉴别诊断。方法:搜集我院9例经手术病理证实的PEA患者的临床及CT检查资料,并进行回顾性分析。结果:9例PEA中,病灶位于乙状结肠旁5例,回盲部1例,升结肠旁1例,降结肠旁2例;9例CT平扫表现为结肠旁卵圆形或分叶状脂肪密度病灶,边缘呈环形高密度影,周围脂肪间隙内均可见条索状高密度渗出影,3例病灶中央见点状高密度影,2例中央见线形高密度影,2例中央可见圆形高密度影,仅2例病灶可见相邻结肠壁的增厚;2例增强扫描病灶边缘呈环状强化。结论:PEA的CT表现具有一定的特征性,CT检查对本病的诊断及鉴别诊断具有重要价值。Objective： To explore the CT appearance and differential diagnosis of primary epiploic appendagitis. Methods：CT manifestations in 9 patients with primary epiploic appendagitis confirmed by pathology were retrospectively an alyzed. Results：The most common part of colon involved by primary epiploic appendagitis was the sigmoid colon,CT scan revealed that there were 5 cases in sigmoid colon, 1 case in ileo-cecal region, 1 case in ascending colon,2 cases in descending colon. The lesions were ovoid or lobulated fatty mass abutting the colon. Hyperattenuated ring with adjacent fat stranding was present in all 9 patients with CT plain scan. The central high attenuation dot was seen in 3 patients,the central high attenuation line in 2 patients,and the central high attenuation core in 2 patients. Colon wall thickening was present in only 2 patients. Ring enhancement could be found in the marginal region of 2 cases with CT contrast scan. Conclusion：Primary epiploic appendagitis has classical CT appearance, CT scan is valuable in the diagnosis and differential diagnosis of primary epi ploic appendagitis.
