Her initial MRI brain revealed pre- and post-septal orbital cellulitis with focal infarction, hyperdense fragments along the lateral orbit which were suspected to be foreign bodies, a linear non-displaced fracture of the posterolateral wall of her right orbit and a filling defect along the anterior and mid aspect of the right cavernous sinus representing a right CSVT (Figure 3).
MRA of CCF: Oblique 3D time-of-flight MRA demonstrates narrowing of the right ICA (white arrow). Focal outpouching extending from ICA (open arrow) reflects the CCF.. MRA: magnetic resonance angiography. CCF: caroticocavernous fistula. ICA: internal carotid artery
