Fig. 6

Right cavernous sinus (CS) and internal carotid artery (ICA) thrombosis. Axial T2-weighted (A), contrast-enhanced axial (B), and coronal (C) T1-weighted fat-saturated images show the bulging lateral border of the right cavernous sinus (white large arrows) with loss of normal flow void of the right internal carotid artery (white small arrows). The right CS shows filling defects on contrast-enhanced images indicating its thrombosis. Note the thickened and enhancing dura (white arrowheads) adjacent to the right temporal lobe. Left intracranial ICA shows normal flow void. Susceptibility-weighted image (D) shows blooming in the petrocavernous part of the right ICA suggestive of the presence of thrombus
