The aim was to compare computed tomography (CT) findings between patients with mesenteric panniculitis (MP) with and without known malignancy.
We retrospectively analyzed 116 consecutive patients who were diagnosed with MP on the basis of CT findings and categorized them according to the absence (Group 1: 73 patients) or presence (Group 2: 43 patients) of malignancy. Patient age and sex, diameter, size, mass effect, location, and fat density of the MP mass, presence of a pseudocapsule and/or halo sign, and lymph node status were compared between the two groups.
MP tends to be more common in males, and this trend shows statistical significance when combining the findings for both groups (=0.041). Patients in Group 1 were significantly younger than those in Group 2 (54.29 vs 64.77 years, =0.001). A well-defined fatty mass at the small bowel root was observed in all patients. The halo sign was present in most cases in both groups. A pseudocapsule was observed in 36 patients (49%) in Group 1 and 29 (67%) in Group 2 (=0.045). The average craniocaudal diameter of the MP masses on the sagittal view was 11.14 and 12.5 cm in Groups 1 and 2, respectively (=0.005). The MP fat density was less negative in patients with malignancy (-66 vs -76 HU, =0.001). Lymph node status was similar in both groups.
Detailed CT features should be evaluated in patients with MP, as some of these features may indicate an associated malignancy, necessitating further investigation and close follow-up.
比较有和没有已知恶性肿瘤的肠系膜脂膜炎（MP）患者的计算机断层扫描（CT）结果。
我们回顾性分析了116例根据CT结果诊断为MP的连续患者，并根据是否存在恶性肿瘤将他们分类（第1组：73例患者）或存在（第2组：43例患者）。比较两组患者的年龄、性别、MP肿块的直径、大小、占位效应、位置和脂肪密度、假包膜和/或晕征的存在情况以及淋巴结状态。
MP在男性中往往更常见，当合并两组的结果时，这种趋势具有统计学意义（=0.041）。第1组患者明显比第2组患者年轻（54.29岁对64.77岁，=0.001）。所有患者均在小肠根部观察到边界清晰的脂肪肿块。两组大多数病例均出现晕征。第1组36例患者（49%）和第2组29例患者（67%）观察到假包膜（=0.045）。矢状面上MP肿块的平均头尾直径在第1组和第2组分别为11.14 cm和12.5 cm（=0.005）。恶性肿瘤患者的MP脂肪密度负值较小（-66对-76 HU，=0.001）。两组的淋巴结状态相似。
对于MP患者应评估详细的CT特征，因为其中一些特征可能表明存在相关的恶性肿瘤，需要进一步检查和密切随访。
