To assess the prevalence and associations of mesenteric panniculitis (MP) using multi-detector CT (MDCT).
This retrospective study included 4758 consecutive patients who underwent abdomino-pelvic MDCT between January 2012 and December 2014 at Jordan University Hospital, Amman, Jordan. Radiological database was searched for MP diagnosis and patients with suspected MP were re-evaluated by an experienced radiologist to confirm the diagnosis. Data on all patients with confirmed MP diagnosis were subsequently collected and analyzed.
Computed tomography features of MP were identified in 90 patients (41 males, 49 females), a prevalence of 1.9%. Mesenteric panniculitis was identified in both asymptomatic and symptomatic patients. Malignancy was found in 28 MP patients (31%) and 44 of the MP patients (49%) had prior history of abdomino-pelvic surgery. Mesenteric panniculitis was significantly more frequently associated with prior abdomino-pelvic surgery (p=0.0001) and the likelihood of associated malignancy in patients with MP was 2.1-fold higher than in patients without MP (p=0.0013). Conclusion: Mesenteric panniculitis can be reliably diagnosed by MDCT due to its typical CT appearance. Its identification is important because of its significant association with malignancy and because it represents one of the differential diagnoses in patients with nonspecific symptoms referred for abdomino-pelvic CT.
使用多排螺旋CT（MDCT）评估肠系膜脂膜炎（MP）的患病率及其相关性。
这项回顾性研究纳入了2012年1月至2014年12月期间在约旦安曼市约旦大学医院连续接受腹盆腔MDCT检查的4758例患者。在放射学数据库中搜索MP诊断信息，疑似MP的患者由经验丰富的放射科医生重新评估以确诊。随后收集并分析所有确诊为MP的患者的数据。
90例患者（41例男性，49例女性）发现有MP的CT特征，患病率为1.9%。无症状和有症状的患者中均发现了肠系膜脂膜炎。28例MP患者（31%）发现有恶性肿瘤，44例MP患者（49%）有腹盆腔手术史。肠系膜脂膜炎与既往腹盆腔手术的相关性显著更高（p=0.0001），MP患者发生相关恶性肿瘤的可能性比无MP患者高2.1倍（p=0.0013）。结论：由于其典型的CT表现，MDCT能够可靠地诊断肠系膜脂膜炎。其识别很重要，因为它与恶性肿瘤有显著相关性，并且它是因非特异性症状接受腹盆腔CT检查患者的鉴别诊断之一。
