We report a rare case of frontal sinus mucocele with a subcutaneous forehead mass. A 62-year-old woman presented with a soft forehead mass. Computed tomography and magnetic resonance imaging revealed a subcutaneous forehead lesion and frontal sinus mucocele, but no communication existed between these lesions. We diagnosed frontal sinus mucocele extending outside the skull through existing defects. After surgery, this subcutaneous lesion was proved to be a subperiosteal hematoma.
Key words : subperiosteal hematoma, extracranial, frontal sinus mucocele
