Diagnosis and treatment of paranasal sinus fungus ball of odontogenic origin: case report.

In recent years the incidence of fungal sinusitis has increased considerably, due both to increased survival of patients at risk and to improved diagnostic equipment. The pathogen responsible in most cases is the Aspergillus in its forms Fumigatus, Flavus and Niger. The diagnosis is often delayed because the symptoms, characterized by headache, cough, and facial algia, are generally similar to that of chronic bacterial rhinosinusitis. It can be divided into invasive and non-invasive forms based on the clinical evolution and extent of the lesion. We report a case of non-invasive fungal rhinosinusitis in a patient with recurrent sinusitis and pain in the left maxillary region, resistant to antibiotic therapy.
