A case of isolated aspergillosis of the maxillary sinus

Aspergillosis of the maxillary sinus is rarely seen in nonimmunocompromised patients. Among paranasal sinus infections associated with aspergillosis, the most common subtype is Aspergillus fumigatus. A 41-year-old woman presented with facial pain. She had a five-year history of root canal filling in the right upper molar teeth. Paranasal sinus tomography showed fungal sinusitis of radiopaque appearance, giving the impression of a foreign body in the maxillary sinus. The patient underwent endoscopic sinus surgery to purge infection of the maxillary sinus. Pathological examination revealed aspergillosis of the maxillary sinus.
