摘要
目的分析肠系膜脂膜炎的CT影像学表现及与其他表现类似疾病的鉴别要点,提高对本病的认识。资料与方法搜集20例肠系膜脂膜炎病例,1例手术证实,其余经临床综合诊断,对所有病例的CT影像学资料进行回顾性分析。结果 20例均发生于小肠系膜,表现为起自肠系膜根部,沿肠系膜血管向腹部延伸的片状影或块状影,可直达肠袢,CT值为-82～-19 HU,增强扫描无明显强化,边缘清晰,周围肠袢可被推移,20例均见结节影及"假包膜征",15例可见"脂环征"。结论多数肠系膜脂膜炎病例可依据CT影像资料明确诊断或与其他疾病鉴别,少数没有特征性表现并难以鉴别的病例可采用手术或穿刺活检明确诊断。
Objective To discuss CT findings and differential diagnosis of mesenteric panniculitis,in order to improve awareness of this disease.Materials and Methods 20 cases of mesenteric panniculitis,1 confirmed by surgery,the remaining consolidated by clinical diagnosis were collected,CT imaging data of all cases were analyzed retrospectively.Results 20 cases occurred in the small bowel mesentery,flaky or massive shadow were showed from the root of mesentery to abdomen,extension along the mesenteric vessels,direct access to intestinal loops,lesion＇s CT value was-82 ^-19 HU,no obvious enhancement was seen,sharp edges,surrounding bowel loops were shifted,nodules and ＂false capsule＂ sign were seen in 20 cases,＂fat ring＂ sign was seen in 15 cases.Conclusion Most of mesenteric panniculitis can be diagnosed based on CT image data or differentiated with other diseases,some cases have no characteristic features and can be diagnosed by biopsy and surgery.
