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.
