case_images: MRI showed prominent cerebrospinal fluid (CSF) spaces in bilateral optic nerve sheaths possibly secondary to bilateral stenosis of transverse sagittal sinuses, with normal ventricular CSF (Figures 1 and 2).
case_images: MRV brain. Asymmetric small caliber of the right transverse sinus is noted, possibly suggesting segment at stenosis versus anatomic variant. There is focal stenosis of the distal left transverse sinus near the sigmoid signus.
