1、萬方數(shù)據(jù)218神經(jīng)影像學(xué)NEUROLOGICALIMAGlNG垂體膿腫MRI診斷張斌1韓芳2錢銀鋒3張家文2馮曉源2【摘要】目的:分析垂體膿腫的MRI表現(xiàn)及其特征,探討MRI表現(xiàn)在診斷中的價值。方法:回顧性分析經(jīng)手術(shù)后、病理或者臨床隨訪證實的垂體膿腫10例,對垂體膿腫的MRI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10例均見垂體高度增加,病灶均位于鞍內(nèi)或向鞍上生長;TlWI呈高信號1例;等高混雜信號3例,高低混雜信號2例,等低混雜信號4例;T2wI呈高信號5例,等高混雜信號3例,2例未行T2WI序列掃描。增強(qiáng)后病灶薄壁環(huán)狀強(qiáng)化6例,厚壁環(huán)形強(qiáng)
2、化4例,其中l(wèi)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仞J。2例行DwI序列掃描,顯示為明顯高信號。結(jié)論:垂體膿腫MR表現(xiàn)具有一定特征性,DwI序列可能對垂體膿腫術(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:R445.2文獻(xiàn)標(biāo)志碼:A文章編號:l006-574l(2014)一03—0218一04MRIFindings0fPituitaryAbscessZHANGBinl,HANFan2,QIANYin—fen93,ZHANGJia—wen2,F(xiàn)ENGXiao—yuan2【Abstract】Pur
