Female, 64 years old, with headaches and history of sarcoidosis. Mild enhancement of the optic chiasm, pre-chiasmatic optic nerves, and the optic tracts is not significantly changed.Scattered patchy areas of previously seen leptomeningeal enhancement along the sulci of the cerebral hemispheres and cerebellum have completely or nearly completely resolved.Focal widening along the right central sulcus is unchanged and may represent the presence of a small arachnoid cyst.Minimal patchy T2 hyperintensity within the pons is unchanged and nonspecific. No significant parenchymal edema or mass effect is detected. No restricted diffusion is seen.No evidence of significant intracranial hemorrhage is seen. The ventricles are stable in size and morphology. Mild coaption of the right frontal horn is unchanged.Large mucus tension cyst remained within the maxillary sinuses, and there is patchy mucosal thickening through the ethmoid air cells.
1.Stable enhancement of the visualized portions of the optic apparatus.2.Interval complete or near complete resolution of previously seen patchy leptomeningeal enhancement.3.No new intracranial lesions.
