目的探讨原发性脑淋巴瘤的MRI与CT检查特点及应用。方法对收治的13例经病理证实的原发性脑淋巴瘤患者的MRI和CT资料进行回顾性分析。结果 13例原发性脑淋巴瘤患者中,9例单发,4例多发,共有病灶21个。CT平扫多表现为等或稍高密度,而MRI平扫时T1WI表现为等或稍低信号,T2WI呈高信号。结论原发性脑淋巴瘤的CT和MRI表现具有一定的特征,对CT和MRI影像资料进行综合分析,有利于原发性脑淋巴瘤的早期诊断。
Objective To investigate the features and applications of MRI and CT in primary brain lymphoma. Methods The MRI and CT data of 13 patients with pathologically proved primary brain lymphoma were retrospectively analyzed. Results Of the 13 patients with primary brain lymphoma, 9 were single and 4 were multiple. There were 21 total lesions. CT scan showed equal or slightly higher density, and MRI plain T1WI showed equal or slightly lower signal, T2WI showed high signal. Conclusion The CT and MRI manifestations of primary brain lymphoma have some characteristics. The comprehensive analysis of CT and MRI images is helpful for the early diagnosis of primary brain lymphoma.
