Frontal sinus infection leading to sino-orbital aspergillosis: a case report

Abstract

Sino-orbital aspergillosis is an uncommon but aggressive infection. It rarely originates from the frontal sinus due to the complex anatomy of the frontal recess and anteromedial position of its ostium. An 87-year-old man of Nigerian heritage with a history of multiple myeloma, chronic kidney disease and type 2 diabetes, presented to the eye clinic with a right tense swollen eyelid and proptosis. Computed tomography (CT) and magnetic resonance imaging (MRI) scan revealed a right superomedial mass communicating with the frontal sinus and biopsy confirmed an orbital aspergilloma. The patient was successfully treated with debulking surgery and anti-fungal treatment despite developing side effects to the drugs. To improve prognosis, ophthalmologists should be aware of this distinct entity and use a multi-disciplinary approach.
