【摘要】：目的通過腹部64層螺旋CT及1.5超導(dǎo)磁共振(MR)對(duì)腸系膜脂膜炎多例影像檢查及診斷的分析,加強(qiáng)對(duì)腸系膜脂膜炎疾病的影像診斷認(rèn)識(shí)。方法 5例中老年腸系膜脂膜炎患者,行64層螺旋CT平掃及增強(qiáng)檢查,其中2例行腹部MR增強(qiáng)及抑脂肪序列檢查。測(cè)量對(duì)比腸系膜病變強(qiáng)化區(qū)域CT值,觀察強(qiáng)化特點(diǎn)及腸系膜血管。結(jié)果 5例患者病變區(qū)域全部來至腸系膜根部范圍,與周圍正常脂肪組織及腸管界線較清楚,2例病變呈云絮狀稍高密度,邊界較清晰,其間少量索條。1例病變區(qū)以軟組織腫塊及纖維化為主,周圍腸管及腸系膜結(jié)構(gòu)稍聚集。2例以纖維索條及小結(jié)節(jié)病變?yōu)橹?血管周圍見"脂肪暈環(huán)征"。4例病變周圍見"假腫瘤包膜"征象。增強(qiáng)檢查病變區(qū)強(qiáng)化不明顯,其中1例腸系膜上動(dòng)脈管腔狹窄,4例病變周圍腸袢推移。增強(qiáng)各期強(qiáng)化范圍15HU。結(jié)論腸系膜脂膜炎多層螺旋CT及MR檢查,影像表現(xiàn)具有一定特征,CT后處理成像技術(shù)可清晰準(zhǔn)確對(duì)病變觀察,為診斷重要手段。
[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.
