case_images: Right ocular ultrasonography in transverse plane.. Papilla protrusion is shown which is suggestive of papilledema indicated by #1. A widened optic nerve sheath diameter (ONSD) of 7.6 mm is indicated by #2 and #3 shows the optic nerve diameter (OND). Both findings are suggestive of elevated intracranial pressure. Not pictured were the results of the ultrasonography of the left eye but were comparable in terms of widened optic nerve sheath diameter and papilledema.

case_images: Given the risk factors for idiopathic intracranial hypertension, an intraocular ultrasound was performed, which showed an optic nerve sheath diameter (ONSD) of 7.6 mm and papilledema, consistent with elevated intracranial pressure (ICP) (Figure 1).
case_images: T1-weighted contrast-enhanced MRI of the brain.. Sagittal reformatted image (A) demonstrating a filling defect within the superior sagittal signal (yellow arrows) consistent with thrombosis. The axial image (B) demonstrates the extent of the thrombosis with extension into the right transverse sinus (blue arrows).

case_images: Neurology was consulted and recommended a magnetic resonance venography (MRV) brain that revealed extensive thrombosis of the superior sagittal sinus from anterior to posterior with extension into the confluence of dural venous sinuses, right transverse sinus, right sigmoid sinus, and right internal jugular vein (Figures 2A, 2B, 3A, 3B).
case_images: MR venography with contrast.. The image in (A) demonstrates an absence of gadolinium contrast filling in the superior sagittal sinus (green arrows) compared to image (B) which shows a normal patent superior sagittal sinus (orange arrows).
