case_images: 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)).

case_images: The tumor was found arising from the upper trunk of the brachial plexus and was found to be adherent to the middle and lower trunk of the brachial plexus (Figure 5(a)). The tumor appeared to be greyish white, firm, and globular (Figure 5(b)).
