摘要 目的探讨脊髓内占位性病变的MRI特点及其鉴别诊断。方法分析病理证实的17例脊髓内肿瘤性占位病变。MRI平扫加增强扫描。比较各类肿瘤的发病年龄、大小、形态、位置、信号及脊髓的变化。结果9例室管膜瘤有5例(56%)起源于胸髓,平均长度为4.5个脊髓节段,4例(44%)出现导致肿瘤信号不均匀的瘤内囊变。5例星形细胞瘤有3例(60%)起源于颈髓,平均长度8个脊髓节段,5例中4例(80%)出现不同程度的瘤内囊变。2例髓内血管母细胞瘤均位于颈髓,平均长度为8.5个脊髓节段,均见瘤内囊变。1例转移瘤累及全胸髓,呈不均匀信号,无明显囊变。结论MRI可反映不同髓内肿瘤的病理特点,据此特点可进行鉴别诊断。
