This study was undertaken to assess the prevalence of mesenteric panniculitis on CT and to describe its appearance and associated diseases.
A total of 7620 consecutive abdominal CT examinations were prospectively evaluated for features common to mesenteric panniculitis such as a well-delineated inhomogeneous hyperattenuated fatty mass at the mesenteric root, envelopment of mesenteric vessels, and no evidence of invasion of the adjacent small-bowel loops that may be displaced.
CT findings of mesenteric panniculitis were seen in 49 patients (0.6%). We found a female predominance. Mesenteric panniculitis coexisted with malignancy in 34 patients and with benign disorders in 11 patients. In the remaining four patients, mesenteric panniculitis, verified on histology, was considered to be responsible for the patients' clinical manifestations; no other abnormality was identified. Soft-tissue nodules (n = 39) and a fatty halo surrounding vessels and nodules (n = 42) were observed in most patients. Follow-up abdominal CT examinations in 29 of the 49 patients showed changes in only one patient.
CT findings of mesenteric panniculitis may be seen in patients undergoing abdominal CT for various symptoms.
本研究旨在评估肠系膜脂膜炎在CT上的患病率，并描述其表现及相关疾病。
对连续7620例腹部CT检查进行前瞻性评估，以寻找肠系膜脂膜炎的常见特征，如肠系膜根部边界清晰的不均匀高密度脂肪肿块、肠系膜血管被包绕，以及无相邻小肠袢受侵及移位的证据。
49例患者（0.6%）出现肠系膜脂膜炎的CT表现。我们发现女性居多。34例患者肠系膜脂膜炎与恶性肿瘤共存，11例与良性疾病共存。其余4例经组织学证实的肠系膜脂膜炎被认为是患者临床表现的原因；未发现其他异常。大多数患者观察到软组织结节（n = 39）以及血管和结节周围的脂肪晕（n = 42）。49例患者中的29例进行了腹部CT随访检查，仅1例有变化。
在因各种症状接受腹部CT检查的患者中可能会出现肠系膜脂膜炎的CT表现。
