Two Cases of Actinomycosis with Aspergillosis in Unilateral Paranasal Sinuses

Abstract

Actinomycosis of paranasal sinus is a very rare disease that is caused by infection of Actinomyces species that were present in oral or nasal flora due to trauma or dental treatment. Actinomycosis shows a local calcified lesion associated with soft tissue density on computed tomography, which is similar to fungal sinusitis. Actinomycosis associated with fungal ball due to Aspergillus affecting sinus ventilation has been rarely reported. We experienced two cases of actinomycosis associated with fungal ball and successfully treated with endoscopic sinus surgery and oral antibiotics for 3 months without recurrence.
