Sphenoid wing meningioma behavior on 11C-PiB and 18F-FDG PET.

AbstractTwo patients with mild cognitive impairment underwent 11C-PiB and 18F-FDG brain PET. Both patients had previously gone through a contrast-enhanced MRI scan that revealed extra-axial tumors next to the sphenoid wing, suggestive of meningiomas. 11C-PiB PET images showed a highly increased upta
