【摘要】：目的探討嬰幼兒視網(wǎng)膜母細(xì)胞瘤(RB)高分辨力MRI表現(xiàn)的特征及其診斷價(jià)值。方法搜集在本院行眼球摘除術(shù)的42例RB患兒術(shù)前MRI資料,對(duì)其中符合入組標(biāo)準(zhǔn)的19例(男11例,女8例,發(fā)病年齡5~36個(gè)月,中位年齡12.5個(gè)月)MR圖像與病理結(jié)果進(jìn)行對(duì)比分析。結(jié)果 19例患兒中,雙眼發(fā)病7例,單眼12例,共26眼受累,多灶5眼,單灶21眼。瘤灶在T1WI呈較稍高或中等信號(hào),T2WI呈低或中等信號(hào),增強(qiáng)后腫瘤呈輕到中度強(qiáng)化。腫瘤呈內(nèi)生型生長者6眼,外生型生長者17眼,浸潤型生長者3眼。與病理對(duì)照MRI對(duì)脈絡(luò)膜受累者診斷的準(zhǔn)確性,敏感性和特異性分別為65.4%,66.6%,63.6%。MRI對(duì)視神經(jīng)受累者診斷的準(zhǔn)確性,敏感性和特異性分別為61.5%,70.0%,56.3%。結(jié)論 MRI對(duì)于RB的診斷具有很高的特異性,能顯示腫瘤向周圍細(xì)微結(jié)構(gòu)的浸潤,可為臨床治療前的分期及制定治療方案提供依據(jù)。
