| 目的 分析脑膜转移瘤的MRI表现特点,探讨MRI对脑膜转移瘤的诊断价值。方法 回顾性分析经手术、病理或脑脊液检查证实的脑膜转移瘤64例。所有病例均行脑MRI平扫和增强扫描。结果 ①MRI平扫:发现脑膜异常改变15例。硬脑膜型9例,其中结节型5例,线状增厚型3例,混合型1例;软脑膜型6例,均为结节型。②MRI增强:64例脑膜转移瘤有3种表现形式:硬脑膜型36例,其中结节型9例,线状增厚型21例,混合型6例;软脑膜型20例,其中结节型10例,线状增厚型7例,混合型3例;全脑膜型8例,其中结节型1例,线状增厚型1例,混合型6例。③其他表现:64例中49例伴脑内转移,12例伴脑积水,6例伴颅骨转移,2例伴皮下转移。 结论 MRI是脑膜转移瘤的重要检查方法,增强MRI对诊断脑膜转移瘤更具有价值。 |

| Objective To analyze the features of MRI manifestation and investigate the value of MRI in diagnosis of meningeal carcinomatosis. Methods Sixty-four cases with meningeal carcinomatosis confirmed by operation and pathology or CSF study were retrospectively analyzed. All cases were examined by plain and contrast MRI. Results ①Plain MRI: abnormal mater changes were found in 15 cases. Dural pattern in 9 cases, including 5 nodular type, 3 linear meningeal thicken type and 1 mixed type. Pia pattern in 6 cases were all nodular type. ②Contrast MRI: 64 cases showed three kinds of manifestation patterns. Dural pattern in 36 cases, including 9 nodular type, 21 linear meningeal thicken type and 6 mixed type. Pia pattern in 20 cases, including 10 nodular type, 7 linear meningeal thicken type and 3 mixed type. Total meninges pattern in 8 cases, including 1 nodular type, 1 linear meningeal thicken type and 6 mixed type. ③Other findings: intracerebral metastases in 49 cases, hydrocephalus in 12 cases, skull metastases in 6 cases and subcutaneous metastasis in 2 cases were found in 64 cases. Conclusion MRI is an important examination method for meningeal carcinomatosis. Post-contrast MRI is better than precontrast MRI in diagnosis of meningeal carcinomatosis. |
