case_images: Fundus image at the initial consultation. Right eye (a) and left eye (b); bilateral optic disc swelling with peripapillary hemorrhage is visualized.

case_images: No abnormalities were observed in the anterior segment of the eye on slit-lamp biomicroscopy, and the fundoscopic examination showed marked redness and swelling of the optic disc in both eyes (Fig. 1).
case_images: Axial T2 magnetic resonance imaging (MRI) of the head. a Bilateral posterior ocular flattening and enlargement of the spinal fluid space in the optic nerve sheath is identified. b Hyperintensity is observed within the superior sagittal sinus (blue arrow), suggesting thrombosis.

case_images: However, T2-weighted imaging horizontal sections revealed flattening of the bilateral posterior ocular surfaces and enlargement of the spinal fluid space in the optic nerve sheath, suggesting intracranial hypertension (Fig. 2a), and a high-signal lesion in the superior sagittal sinus, suggesting a thrombus (Fig. 2b).
case_images: Magnetic resonance venography (MRV) Absence of signal (blue arrows) in parts of the superior sagittal (a, b) and left transverse (a) sinuses.

case_images: Magnetic resonance venography (MRV) revealed a shadow defect extending from the superior sagittal sinus to the left transverse sinus (Fig. 3).
