目的探讨原发性颅内淋巴瘤的MRI、CT表现特征。方法:回顾分析13例经病理证实的单发原发颅内淋巴瘤的MRI、CT表现。结果12例病变位于幕上,1例病变位于幕下。CT多表现为等或稍高密度肿块,T1WI呈等或稍低信号,T2WI呈等、低或稍高信号,信号多均匀,瘤周水肿较明显。CT和MRI增强扫描肿块均明显强化,边缘光整或呈分叶状,坏死囊变、钙化少见。结论颅内淋巴瘤的MRI、CT表现有一定特征性,通过认真的影像分析,在术前作出正确诊断是可能的。
Objective To investigate the MRI and CT features of primary intracranial lymphomas. Methods: MRI and CT findings of 13 cases of single primary intracranial lymphomas confirmed by pathology were retrospectively analyzed. Results Twelve lesions were located on the screen, one was located in the screen. CT showed the same or slightly higher density mass, T1WI was equal or slightly lower signal, T2WI was equal, low or slightly higher signal, the signal more uniform, more obvious peritumoral edema. CT and MRI enhanced scan mass were significantly enhanced edge or round lobular, necrotic cystic change, calcification rare. Conclusion MRI and CT findings of intracranial lymphomas have certain characteristics. It is possible to make correct diagnosis before surgery by careful image analysis.
