【摘要】：目的:探讨硬化性肠系膜炎的典型及非典型影像学表现,以提高对该病的认识。方法:回顾性分析经临床病理证实的29例硬化性肠系膜炎患者的CT和MRI资料。结果:(1)典型表现(27例):病变均起自肠系膜根部,包绕肠系膜血管,其中15例呈雾状系膜,12例显示假肿瘤征,21例可见假包膜,17例可见脂肪环征。CT平扫表现为肠系膜密度增高,CT值为-66~-38HU,明显高于腹膜后正常脂肪密度(-160~-100HU),差异有统计学意义(P0.05)。MRI平扫表现病变呈不均匀长T1、长T2信号,假包膜呈等T1、短T2信号。CT、MRI增强扫描病变呈轻度强化,假包膜呈轻度延迟强化。(2)非典型表现(2例):1例表现为肠系膜周围多发小结节,1例表现为肠系膜周围散在钙化灶。结论:硬化性肠系膜炎具有典型和非典型影像学表现,临床与影像学表现相结合有助于提高对本病的诊断。
[Abstract]:Objective: to investigate the typical and atypical imaging manifestations of sclerosing mesenteritis. Methods: Ct and MRI data of 29 patients with sclerosing mesositis confirmed by clinical pathology were analyzed retrospectively. Of them, 15 cases showed foggy Mesangium, 12 cases showed false tumor sign. 21 cases showed pseudocapatite sign. 17 cases showed fat ring sign. Ct plain scan showed that the density of mesentery was increased. Ct value was -66 ~ 38 HU. it was obviously higher than that of retroperitoneal normal fat density of -160 ~ 100 HUU, the difference was statistically significant. P0.05, MRI plain scan showed uneven long T _ 1, long T _ 2 signal intensity, and long T _ 2 signal intensity. Pseudocapsule showed iso-T _ 1, short T _ 2 signal. CTU enhanced MRI showed slight enhancement. The pseudocapsule presented mild delayed enhancement. (2 cases: 1 case showed multiple small nodule around the mesentery and 1 case showed calcified foci around the mesentery. Conclusion: sclerosing mesenteritis has typical and atypical imaging manifestations. The combination of clinical and imaging findings is helpful to improve the diagnosis of this disease.
