case_images: Magnetic resonance imaging of the brain revealed (a) a 4.3 cm lesion occupying the superior portion of the left cavernous sinus and (b and c) extending into the left intraconal space. (d) It displayed heterogeneous enhancement on contrast imaging.

case_images: Magnetic resonance imaging (MRI) of the brain revealed a T2w-hyperintense lesion occupying the superior portion of the left cavernous sinus [Figure 1a], extending into the intraconal space. It measured 4.3 cm in maximum dimension [Figures 1b and c], demonstrating heterogeneous contrast enhancement [Figure 1d].
case_images: (a) A post-operative day 3 magnetic resonance imaging brain revealed a large T1 hypointense, (b) T2 hyperintense extradural collection, 2.1 cm in width. Following evacuation of the collection, he did not develop any new symptoms; (c and d) however, a post-operative computed tomography revealed recollection in the subdural space, 1.3 cm thick, shifting the midline and nearly obliterating the left lateral ventricular system which was managed with simultaneous burr-hole evacuation of the collection and an epidural blood patch, (e and f) following which there was no recollection.

case_images: Incidentally, it revealed an extradural collection, 2.1 cm wide causing uncal herniation [Figure 2a and b]. A CT scan 6 days later demonstrated evacuation of the subdural collection, with a resolution of mass effect [Figure 2e and f].
