1、多發(fā)性骨髓瘤免疫學(xué)分型及其臨床與MRI表現(xiàn)論文【關(guān)鍵詞】多發(fā)性骨髓瘤免疫球蛋白磁共振成像診斷多發(fā)性骨髓瘤(MM)是漿細(xì)胞異常增生導(dǎo)致的惡性腫瘤,由具有合成與分泌免疫球蛋白能力的漿細(xì)胞克隆性惡性增生所致,侵犯骨髓及骨質(zhì)可產(chǎn)生溶骨性病變,并可合成與分泌大量結(jié)構(gòu)單一的單克隆免疫球蛋白或其輕鏈,引起骨骼疼痛、病理性骨折、貧血、出血、腎功能損害、反復(fù)感染等一系列臨床表現(xiàn)。占血液系統(tǒng)惡性疾病的10%左右[1]。發(fā)病男性多于女性,男女比例約3∶2;平均發(fā)病年齡約65歲,小于40歲者僅占2%左右。本文對(duì)MM的免疫學(xué)分型及影像學(xué)表現(xiàn)綜述如下。1MM免疫學(xué)分型及其臨床、實(shí)驗(yàn)室特點(diǎn)MM是單克隆的B細(xì)胞
