title: Fibrosis surrounding a silicone implant simulating recurrent orbital meningioma. Case report.
abstract: A patient with the preoperative diagnosis of recurrent orbital apical meningioma was found to have a fibrotic capsule surrounding a silicone plate implanted 3 years previously to reconstruct the orbital roof. Caution is urged in using alloplastic orbital implants for reconstructive purposes in patients undergoing orbital surgery, because associated fibrous capsule formation may mimic tumor recurrence.
