Initial brain MRI demonstrated T2\/FLAIR hyperintense signal abnormality in the pons extending along the middle cerebellar peduncles into the cerebellum, with associated punctate, patchy, and linear enhancement on postcontrast imaging. Initially, this was attributed to brainstem encephalitis; however, sarcoidosis, histiocytosis, and paraneoplastic\/autoimmune encephalitis remained on the differential. One month after initial MRI, <jats:sup>18<\/jats:sup>F-FDG brain PET\/MRI was performed and showed marked pontine hypermetabolism corresponding to the signal abnormality and enhancement on structural imaging.
