摘　　要：目的分析肠系膜脂膜炎(MP)的CT影像学特征,探讨其与恶性肿瘤的关系。方法回顾性分析37例MP患者的临床及CT影像学资料。结果 37例MP患者中,24例(64.86%)没有明显症状,13例(35.14%)有症状者常见症状为腹痛(10/13)、腹胀(6/13)、体质量下降(5/13)。CT扫描均显示小肠系膜脂肪密度增高,伴多发小结节,假包膜征见于23例患者(62.16%),脂肪环征见于20例患者(54.05%)。37例患者中,21例(56.76%)发生于恶性肿瘤患者,16例(43.24%)为非肿瘤患者。结论 MP患者多数不具有明显症状,而具有比较典型的CT影像学特征,且多数患者伴发恶性肿瘤,MP可能是恶性肿瘤的伴随现象。若CT发现MP,有必要进一步明确患者是否患有恶性肿瘤。Objective To analyze the CT imaging features of mesenteric panniculitis （MP） and to explore the possible association between MP withmalignancy. Methods A retrospective analysis of clinical data and CT imaging data of 37 cases of MP patients were performed. Results MP was symptomatic in 13 patients （35.14%）. The common symptom was abdominal pain （10（13）, abdominal distension （6/13） and weight loss （5/13）. Other 24 patients（64.86%） were asymptomatic. Hyper-attenuation of mesenteric fat and the presence of subcentimeter lymph nodes werevisible on CT in all patients. Pseudocapsule and fat halo sign were visible in 23/37 （62.16%） and 20/37 （54.05%） respectively. Malignancy was present in 21 patients （56.76%）. 16 cases of patients （43.24%） were non-tumor patients. Conclusion MP was asymptomatic in most patients, while MP had typical CT appearance and was associated with malignancy in most patients. The association might suggest that MP may be considered as a paraneoplastic phenomenon： So, further examination is necessary performed for presence of synchronous malignancy when incidental depiction of MP visible on CT in a patient without known malignancy.
