title: Giant Cell Tumor of the Frontal Bone Presenting as an Orbital Mass.
abstract: A 10-year-old male was referred for evaluation of a right orbital mass present for 3 weeks with associated tenderness to palpation. Magnetic resonance imaging (MRI) and computed tomography imaging (CT) revealed a solid mass centered in the frontal bone with extension into the orbit. Surgical excision and histologic analysis of the lesion was consistent with a diagnosis of a Giant Cell Tumor (GCT) of the frontal bone. The patient tolerated the procedure without complication and is doing well upon follow-up.
