title: A rare localization of pure dermoid cyst in the frontal bone.
abstract: We report the case of an 84-year-old woman who came to our attention with right palpebral edema associated with pain in the omolateral fronto-orbital region. The patient underwent an MRI scan that revealed a rounded, extracerebral intradiploic cystic lesion with dyshomogeneous signal intensity. Computed tomography (CT) imaging was also performed with reformatted 3D reconstruction. Post-surgical histologic analysis confirmed the diagnosis of intradiploic dermoid cyst. We here report the case and discuss epidemiology, imaging features and work-up of this pathological entity.
