Abstract

While the imaging modality of choice to diagnose neurosarcoidosis is gadolinium-enhanced MRI, 18F-FDG PET/CT maybe used to stage the disease or target the optimal biopsy site. Few cases have described intense 18F-FDG uptake at the sites of active neurosarcoidosis in the midbrain and pituitary gland, cerebellar hemispheres, and temporal lobes. Here, we present a case of neurosarcoidosis whose PET/CT examination demonstrated 18F-FDG avidity in a dural plaque.
