| 摘 要： | 目的:分析垂体脓肿的CT和MR表现特征,以提高诊断的准确性。方法:对经过手术病理证实的12例垂体脓肿的CT和MR资料,结合文献进行回顾性分析。结果:CT平扫呈等或低密度,MR平扫T1WI呈等低或等高混杂信号,T2WI呈高信号或高低混杂信号,7例MR增强后呈均匀薄环状强化。12例中3例见正常垂体,3例垂体柄增粗强化,2例伴邻近脑膜轻度强化,5例伴副鼻窦炎。结论:垂体脓肿症状、体征及CT和MRI表现与其他鞍区囊性病变不易鉴别,但是根据增强前后的特征性表现,有可能在术前作出正确诊断。

| Abstract: | Objective:To study the CT and MRI features of pituitary abscess and to improve its diagnostic accuracy.Methods:CT and MR findings in 12 patients with pituitary abscess proved by surgery and pathology were analyzed retrospectively.Results:The lesions appeared isodensity or hypodensity on CT plan scan,iso-hypointense or iso-hyperintense heterogeneous intensity on T1WI,and hyperintense or hyper-hypointense on T2WI.7 cases showed thin ring-like enhancement in MR enhancement scan.Normal pituitary gland was seen ... |
