Coexistent Actinomycosis and Fungus Ball in the Maxillary Sinus: A Case Report

Abstract

Actinomycosis is rarely accompanied by fungus balls. It is difficult to distinguish between actinomycosis and a fungus ball due to their similar clinical and computed tomography scan results. Thus, a meticulous histopathological examination is required for definite diagnosis. We report a case of actinomycosis accompanied by a fungus ball, found incidentally in a patient without rhinologic symptoms. The patient was successfully treated with endoscopic sinus surgery, followed by short-term antibiotic therapy. We suggest that shortterm antibiotic therapy may be more appropriate than long-term antibiotic therapy based on our case study as well as several other studies.
