There is hyperintense FLAIR signal seen within the sulci of the occipital lobes and folia of the cerebellum. No related abnormalities could be detected at T1, T2, T2* or DWI images, which indicates this signal is not blood. Following contrast administration, there is leptomeningeal enhancement best seen within the cerebellar folia, anterior temporal regions bilaterally, lining the cerebellar tonsils, and at the interpeduncular fossa.
