PURPOSE
Isolated amyloidoma rarely involves the nervous system.
MATERIALS
We report a patient with progressively worsening triparesis and numbness in his extremities.
RESULTS
Magnetic resonance imaging (MRI) of the brain revealed a mass lesion involving both hemispheres, which on positron emission tomography (PET) scan and magnetic resonance-spectroscopy (MR-SPECT) appeared to be a butterfly glioma. However, neuropathological examination revealed a large area with localized vascular amyloidosis.
CONCLUSION
This is the first case of a localized central nervous system vascular amyloid to imitate a butterfly glioma on MRI and PET scan studies.
目的
孤立性淀粉样瘤很少累及神经系统。
材料
我们报告了一名患者，其四肢出现进行性加重的三肢轻瘫和麻木。
结果
脑部磁共振成像（MRI）显示双侧半球有一个肿块病变，正电子发射断层扫描（PET）和磁共振波谱（MR-SPECT）显示该病变似乎是一个蝶形胶质瘤。然而，神经病理学检查发现大面积的局限性血管淀粉样变性。
结论
这是首例在MRI和PET扫描研究中表现为模仿蝶形胶质瘤的局限性中枢神经系统血管淀粉样变性病例。
