case_images: T2 fat saturated oblique saggital image through the optic nerve (a, b) shows the optic nerve buckling with prominent perioptic subarachnoid space (a). Post-LP, the optic nerve straightens with some reduction in the perioptic fluid (b)

case_images: Saggital oblique images through the optic nerve revealed distended perioptic subarachnoid space as well as buckling of the orbital portion of the optic nerve [Figure 1a]. Repeat MRI done 3 days later showed straightening of the intraorbital optic nerve and reduction in perioptic subarachnoid space [Figure 1b].
case_images: Saggital images of the sella show "partial empty sella" (a), which, following CSF drainage, is normalized (b)

case_images: A partial empty sella with postero-inferiorly compressed pituitary having a concave superior border and posteriorly displaced infundibulum was also noted [Figure 2a]. In addition, restoration of the infundibular position with a normal appearing pituitary having a flat superior margin was seen [Figure 2b].
case_images: Paucity of the cortical veins and non visualized right transverse sinus (a) is reversed following CSF drainage with distension of the sinuses and better visualization of the cortical veins (b) in this TOF venogram.

case_images: TOF venography showed paucity of the cortical veins and non-visualization of the right transverse sinus (TS) [Figure 3a]. TOF showed improved visualization of the cortical veins and right TS [Figure 3b]. The patient was discharged on acetazolamide, and on follow-up at 2 and 6 months, was asymptomatic.
