Key Clinical MessageNeurosarcoidosis represents a significant diagnostic challenge, as clinical features overlap with other neuroinflammatory conditions, and biopsy of affected neuronal tissue is often high risk or not feasible. Here we highlight application of the modified Zajicek criteria to diagnose probable spinal neurosarcoidosis in the absence of histology from affected neuronal tissue.

BACKGROUND AND PURPOSE: Small oral cavity tumors are an imaging challenge. Intimate apposition of vestibular oral mucosa to the alveolar mucosa makes tumor assessment difficult. In CT imaging, the "puffed cheek" method has been used to separate surfaces, though this is not feasible with long MR imaging sequences. We implemented placement of 2 ϫ 2 inch (6.45 cm) gauze into the oral vestibule before the MR imaging examination, to determine whether this might improve tumor visualization.
