Legend T2-weighted axial images reveal hyperintensity in the optic chiasm and tracts.

Legend FLAIR images confirm involvement of the visual pathways and additional areas in the hypothalamus and right perisylvian cortex. Axial T2 images at the level of the IAC show a low signal, lobulated mass in the right cerebellar pontine angle with mass affect on the brainstem.

Legend After contrast administration thick nodular areas of meningeal and dural enhancement are seen in the right sylvian fissure, chiasm, along the falx, and in the right greater than the left cerebellar pontine cisterns.

Legend Additional contrast images show abnormal enhancement in the right sylvian fissure, suprasellar cisterns, interpeduncular cistern, and CP angles. Key words: mri inflammation systemic
