ABSTRACT

Osteomas are benign slow growing tumours of the paranasal sinuses. The frontal and ethmoidal sinuses are most commonly affected. We present an unusual case of a 42-year-old Malay lady who had a frontal lobe mucocoele, secondary to an extensive frontal sinus osteoma with orbital and intracranial extension, and presenting primarily with orbital proptosis. She was successfully managed by a multi-specialty team.

Keywords: Frontal sinus, mucocoele, osteoma, proptosis, intra-cranial extension
