Aspergillosis of the frontal sinus.

Aspergillus is the most common fungal infection of the paranasal sinuses and usually appears as a chronic disease in an otherwise healthy person. Previously reported cases have involved the maxillary sinus alone in the majority of cases. To my knowledge, isolated frontal sinus aspergillosis has not been previously reported. A frontal osteoplastic flap approach was used to expose a fungus ball in the right frontal sinus of a healthy 69-year-old man. Histologic preparations and fungal cultures showed Aspergillus fumigatus. Follow-up substantiated prior experience that surgical removal of the fungal mass with drainage of the involved sinus is the treatment of choice in healthy patients with Aspergillus involving the paranasal sinuses.
