硬化性肠系膜炎的CT和MRI诊断

目的探讨硬化性肠系膜炎的CT和MRI表现特征。方法回顾性分析6例经病理证实的硬化性肠系膜炎的CT和MRI表现。结果 6例硬化性肠系膜炎均起自肠系膜根部,包绕肠系膜血管。CT表现为肠系膜根部密度增高,边缘模糊,CT值-10～20HU,明显高于腹膜后脂肪组织密度(-120～-100HU)。MRI表现为不均匀长T1、长T2信号。增强呈轻度延迟期强化,肠系膜血管无浸润。结论硬化性肠系膜炎具有一定的CT和MRI表现特征,确诊需依赖病理。

Diagnosis of sclerotic mesenteritis with CT and MRI

Objective To investigate the character of CT and MRI in the diagnosis of sclerosing mesenteritis(SM).Methods The CT and MRI manifestations of the six patients with sclerosing mesenteritis were analyzed retrospectively.Results All of the six patients with SM with high density originated from the mesenteric blood vessels.The value of mesentery ranged from-40~20 HU on plain CT and were higher than that of retroperitoneal adipose tissue in the same patients(-120~-100 HU).Longer T1 and T2 of messages appeared on MRI.Mild delayed phase enhanced and did not violate mesenteric blood vessels on CT and MRI with enhanced scan.Conclusion Sclerosing mesenteritis has certain characters of CT and MRI and its definite diagnosis relies on pathology.
