【摘要】：目的通过腹部64层螺旋CT及1.5超导磁共振(MR)对肠系膜脂膜炎多例影像检查及诊断的分析,加强对肠系膜脂膜炎疾病的影像诊断认识。方法 5例中老年肠系膜脂膜炎患者,行64层螺旋CT平扫及增强检查,其中2例行腹部MR增强及抑脂肪序列检查。测量对比肠系膜病变强化区域CT值,观察强化特点及肠系膜血管。结果 5例患者病变区域全部来至肠系膜根部范围,与周围正常脂肪组织及肠管界线较清楚,2例病变呈云絮状稍高密度,边界较清晰,其间少量索条。1例病变区以软组织肿块及纤维化为主,周围肠管及肠系膜结构稍聚集。2例以纤维索条及小结节病变为主,血管周围见"脂肪晕环征"。4例病变周围见"假肿瘤包膜"征象。增强检查病变区强化不明显,其中1例肠系膜上动脉管腔狭窄,4例病变周围肠袢推移。增强各期强化范围15HU。结论肠系膜脂膜炎多层螺旋CT及MR检查,影像表现具有一定特征,CT后处理成像技术可清晰准确对病变观察,为诊断重要手段。
[Abstract]:Objective to analyze the imaging diagnosis of mesenteric panniculitis by 64 slice spiral CT and 1. 5 superconducting magnetic resonance (MR) in order to enhance the diagnosis of mesenteric panniculitis. Methods 5 cases of mesenteric panniculitis were examined by 64 slice spiral CT plain scan and contrast enhancement, 2 of them underwent abdominal Mr enhancement and fat suppression sequence examination. The CT value of enhanced mesenteric lesions was measured and the enhancement characteristics and mesenteric vessels were observed. Results all the lesion areas came to the mesenteric root in all of the 5 patients. The boundary between the lesions and the surrounding normal adipose tissue and intestinal canal was clear. 2 cases showed cloud flocculating slightly high density, and the boundary was clear. The soft tissue masses and fibrosis were the main lesions in the lesion area of 1 cases with a small number of cord strips, and the lesions of fibrous cord strip and small nodule were the main lesions in the surrounding intestinal tract and mesenteric structure of 2 cases. The perivascular sign of adipose halo ring was seen in 4 cases with pseudotumor capsule around the lesion. Enhancement was not obvious in the lesion area, including 1 case of superior mesenteric artery stenosis and 4 cases of intestinal loops around the lesion. The range of enhancement was 15HU. Conclusion Multi-slice spiral CT and Mr imaging of mesenteric panniculitis can be used as an important method for diagnosis of mesenteric panniculitis.
