A 79-year-old woman with a history of hypertension and recent facial trauma secondary to a mechanical fall 2 months earlier presented to the emergency department with the acute onset of left eye pain and facial swelling. Physical examination revealed left periorbital erythema with associated soft-tissue edema, ptosis of the left upper eyelid, and hypoesthesia in the left V2 distribution. Computed tomographic imaging of the orbit and paranasal sinuses demonstrated an expansile cystic lesion within the left zygoma (Figure 1 and Figure 2). Also, magnetic resonance imaging showed a cystic heterogeneous nonenhancing expansile mass of the left zygoma, with associated preseptal cellulitis (Figure 3 and Figure 4).
