【摘要】：目的:為了提高對(duì)兒童髓母細(xì)胞瘤影像診斷的準(zhǔn)確率,本文主要探討兒童髓母細(xì)胞瘤的CT及MRI影像學(xué)表現(xiàn)。方法:回顧性分析了62例兒童髓母細(xì)胞瘤的CT及MRI影像資料。其中男43例、女19例,年齡2~18歲。62例均進(jìn)行了MR掃描,51例又進(jìn)行了CT掃描。62例全部經(jīng)手術(shù)、病理證實(shí)。結(jié)果:62例髓母細(xì)胞瘤中56例位于小腦蚓部,6例位于小腦半球,其中18例累及四腦室側(cè)孔區(qū);47%的病例腫瘤中發(fā)現(xiàn)鈣化;MR掃描8例呈等T1等T2信號(hào),54例呈長(zhǎng)T1長(zhǎng)T2信號(hào),61例呈不同程度的不均勻強(qiáng)化。影像報(bào)告診斷準(zhǔn)確率為60%。結(jié)論:兒童髓母細(xì)胞瘤有其典型的好發(fā)部位及特征性影像表現(xiàn),掌握其影像學(xué)特點(diǎn)及鑒別診斷要點(diǎn),可以提高影像診斷的準(zhǔn)確率,降低誤診率。
[Abstract]:Objective: to improve the accuracy of imaging diagnosis of medulloblastoma in children, CT and MRI findings of medulloblastoma in children were studied. Methods: Ct and MRI images of 62 children with medulloblastoma were retrospectively analyzed. Among them, 43 males, 19 females, aged 218 years and 62 cases, underwent Mr scan in 51 cases and CT scan in 51 cases, all of which were proved by operation and pathology. Results of 62 cases of medulloblastoma, 56 cases were located in the cerebellar vermis and 6 cases were in the cerebellar hemisphere. Of the 18 cases involving 47% of the tumors in the lateral foramen of the fourth ventricle, 8 cases showed iso-T1 iso-T2 signal intensity, 54 cases showed long T1 and long T2 signal intensity and 61 cases showed heterogeneous enhancement in varying degrees. The diagnostic accuracy of image report was 60%. Conclusion: medulloblastoma in children has its typical predilection location and characteristic imaging features. Mastering its imaging features and differential diagnosis points can improve the accuracy of imaging diagnosis and reduce the misdiagnosis rate.
