目的:探讨颅底B细胞性非霍奇金淋巴瘤的影像学特点。方法:报道2例颅底B细胞性非霍奇金淋巴瘤,并结合文献对其影像学特征进行总结分析。结果:颅底B细胞性非霍奇金淋巴瘤的影像学表现为T2加权等或低信号,MRI肿瘤强化不明显,颅内侵犯软组织的宽度远大于颅底骨质的破坏范围并沿硬脑膜浸润。结论:颅底B细胞性非霍奇金淋巴瘤具有特征性的影像学表现,对该疾病的诊断和鉴别诊断有一定意义。
Objective: To investigate the imaging characteristics of skull base B cell non-Hodgkin’s lymphoma. Methods: Two cases of skull base B - cell non - Hodgkin ’s lymphoma were reported, and their imaging features were summarized and analyzed. Results: The images of skull base B-cell non-Hodgkin’s lymphoma showed T2 weighted or low signal. MRI showed no obvious tumor enhancement. The width of soft tissue infiltration in the skull base was much larger than that of the skull base. infiltration. Conclusion: Skull base B-cell non-Hodgkin’s lymphoma has the characteristic radiological manifestations, which is of certain significance for the diagnosis and differential diagnosis of this disease.
