He was brought with reduced GCS, fever, and agitation. Empirically managed as meningoencephalitis. Non-contrast CT was reported normal. Contrast CT was performed to exclude cerebral abscess: Generalized sulcal effacement with mild generalized leptomeningeal enhancement, raising the possibility of meningoencephalitis.
