目的:分析髓母细胞瘤的MRI影像学特点。方法:搜集经手术病理证实的髓母细胞瘤12例,行MRI检查。其中男9例。女3例,年龄3岁～17岁。10岁以下患者7例(58%)。结果:髓母细胞瘤好发于男性儿童,常见于小脑蚓部。MRI扫描T_1加权像呈等或稍低信号,T_2加权像呈等或略高于脑灰质信号,注药后呈中等至明显强化。结论:磁共振影像学检查可以有效的诊断髓母细胞瘤。
Objective: To analyze the MRI features of medulloblastoma. Methods: 12 cases of medulloblastoma confirmed by surgery and pathology were collected for MRI examination. Nine of them were male. 3 females, aged 3 to 17 years old. Seven patients (58%) under 10 years of age. Results: Medulloblastoma occurred in male children, common in cerebellar vermis. MRI scan T_1 weighted image was equal or slightly lower signal, T_2 weighted image was equal to or slightly higher than the gray matter signal, the injection was moderate to significantly enhanced. Conclusion: Magnetic resonance imaging can effectively diagnose medulloblastoma.
