case_images: Initial exam. Optical coherence tomography (OCT) with quantification of optic nerve/retinal nerve fiber layer (RNFL) thickness edema right eye. No macular edema. Humphrey visual field (HVF) stimulus V 24-2 OD showing incomplete superior and inferior altitudinal defect OD; stimulus III 30-2 OS normal.. Abbreviations: OD, right eye; OS, left eye.

case_images: MRI orbits and brain. Upper panel shows MRI T2 high definition showing the right optic nerve head thickening (arrows). No enhancement or hyperintensity of nerve. Lower panel shows MRI brain T1 with contrast with positive nonspecific diffuse pachymeningeal thickening(arrow heads) without nodularity.. Abbreviation: MRI, magnetic resonance imaging.

case_images: MRI brain and orbit, brain MRV, and repeated lumbar puncture. Magnetic resonance imaging showed diffuse leptomeningeal enhancement and thickening without nodularity (Figure 2); MRV was unremarkable, and venous sinus thrombosis was ruled out.
