Contrast-enhanced CT (CECT) scan with cisternography revealed a large lobulated mass of size 81 x 53 x 82 mm in the left zygomatic and masseteric region with intracranial extension (Figure 1(a)). Postoperatively, patient had an uneventful recovery, with minimal left eye vision improvement (Figure 1(b)).
