| 中文摘要: |
| 目的 探讨MRI对原发性脑内恶性淋巴瘤的诊断价值。方法 回顾性分析8例经手术和病理证实的脑内恶性淋巴瘤患者的MR表现。结果 MRI表现为:①T1WI呈等或稍低信号灶,T2WI为等或稍高信号,多数肿瘤轻至中度水肿和占位效应;②Gd-DTPA增强扫描肿瘤呈均匀或不均匀强化。结论 MRI的多轴位成像及Gd-DTPA应用有助于脑内恶性淋巴瘤的诊断与鉴别诊断并有助于减少误诊。 |

| Objective To investigate the role of MRI in diagnosis of primary malignant lymphomas in the brain.Methods Eight cases of primary malignant lymphomasin the brain proved by operation and pathology were examined by MRI before operation.MRI features were analysed retrospectively.Results The MRI appearances were as following:①On T1WI,the lesions were isointense or slightly hypointense while isointense or slightly hyperintense on T2WI.Most lymphomas in the brain showed minimal or moderate edema and mass effect; ②Homogeneous or inhomogeneous Gd-DTPA enhancement presented in most of the tumors.Conclusion Multiplanar imaging and Gd-DTPA enhancement in MRI are helpful in diagnosis and differential diagnosis of primary malignant lymphomas in the brain.Therefore,misdiagnosis could be decreased. |
