【摘要】：目的觀察致癲癇性顳葉內(nèi)側(cè)腫瘤的MRI表現(xiàn)。方法回顧性分析28例經(jīng)病理證實為致癲癇性顳葉內(nèi)側(cè)腫瘤患者的臨床及MRI資料,對比觀察不同病理類型病灶的位置、直徑、信號等MRI表現(xiàn)。結(jié)果 28例中,神經(jīng)元及混合性膠質(zhì)-神經(jīng)元腫瘤21例(21/28,75.00%),膠質(zhì)瘤5例(5/28,17.86%),腦內(nèi)海綿狀血管瘤2例(2/28,7.14%)。23例腫瘤位于杏仁核-海馬區(qū),5例位于顳葉內(nèi)側(cè)其他區(qū)域。與膠質(zhì)瘤相比,神經(jīng)元及混合性膠質(zhì)-神經(jīng)元腫瘤直徑多2cm(χ2=6.62,P=0.034),且瘤周水腫不明顯(χ2=6.62,P=0.034)。28例中,18例發(fā)生囊變,9例發(fā)生鈣化,不同病理類型腫瘤間囊變的發(fā)生率、囊變特點及鈣化發(fā)生率差異均無統(tǒng)計學(xué)意義(P均0.05)。共15例合并FCD,神經(jīng)元及混合性膠質(zhì)-神經(jīng)元腫瘤較其他病理類型更易并發(fā)FCD(χ2=5.791,P=0.029)。結(jié)論致癲癇性顳葉內(nèi)側(cè)腫瘤MRI表現(xiàn)具有一定的特征,病理類型以神經(jīng)元及混合性膠質(zhì)-神經(jīng)元腫瘤最為多見。
