case_images: CT of the orbits with contrast showed swelling of the left preseptal periorbital soft tissue, intraorbital fat stranding more prominent on the left compared with the right and opacification of bilateral maxillary sinuses (figure 1).
case_images: MRI of the orbits. MRI of the orbits in the axial plane including postcontrast T1-weighted fat-saturated images. Periorbital and retrobulbar oedema with distention of the superior ophthalmic vein especially prominent on the left side (asterisk) and a non-enhancing lesion in the left lateral intraconal space concerning orbital thrombophlebitis (red arrow). Asymmetrically thick enhancement along the margins of the left cavernous sinus and subtle hypoenhancement within the left posterolateral cavernous sinus suggests cavernous sinus thrombosis (yellow arrow).

case_images: MRI of the head and orbits performed with and without contrast demonstrated periorbital and retrobulbar oedema with distention of the superior ophthalmic veins especially on the left side, and a non-enhancing lesion in the left lateral intraconal space, concerning orbital thrombophlebitis (figure 2). There was asymmetrically thick enhancement along the margins of the left cavernous sinus, with subtle hypoenhancing foci within the posterior portion, concerning cavernous sinus thrombosis (figure 2).
