1、神經(jīng)影像學(xué)218NEUROLOGICALIMAGING垂體膿腫MRI診斷張斌韓芳錢銀鋒張家文馮曉源【摘要】目的:分析垂體膿腫的MR/表現(xiàn)及其特征,探討MRI表現(xiàn)在診斷中的價(jià)值。方法:回顧性分析經(jīng)手術(shù)后、病理或者臨床隨訪證實(shí)的垂體膿腫1O例,對(duì)垂體膿腫的MR/表現(xiàn)進(jìn)行分析,結(jié)合文獻(xiàn)討論垂體膿腫DwI表現(xiàn)。結(jié)果:所有1O例均見垂體高度增加,病灶均位于鞍內(nèi)或向鞍上生長(zhǎng);TIWI呈高信號(hào)1例;等高混雜信號(hào)3例,高低混雜信號(hào)2例,等低混雜信號(hào)4例;T2WI呈高信號(hào)5例,等高混雜信號(hào)3例,2例未行T2WI序
2、列掃描。增強(qiáng)后病灶薄壁環(huán)狀強(qiáng)化6例,厚壁環(huán)形強(qiáng)化4例,其中1例厚壁環(huán)形強(qiáng)化伴有分隔強(qiáng)化;伴有視交叉受壓5例;伴軟腦膜強(qiáng)化3例。2例行DWI序列掃描,顯示為明顯高信號(hào)。結(jié)論:垂體膿腫MR表現(xiàn)具有一定特征性,DWI序列可能對(duì)垂體膿腫術(shù)前診斷和鑒別診斷具有重要意義。【關(guān)鍵詞】垂體膿腫;磁共振成像;彌散加權(quán)成像中圖分類號(hào):R445.2文獻(xiàn)標(biāo)志碼:A文章編號(hào):1006—5741(2014).03.0218.04MRIFindingsofPituitaryAbscessZHANGBin,HANFan。,QI
