Fungal ball-type maxillary sinusitis associated with Penicillium species: A case report and management perspective.

Penicillium is a diverse genus of fungus that widely exists in the environment and is often non-pathogenic. Only a handful of literature have reported its association as a cause of infection in humans. Here, we report a case of a Penicillium maxillary sinus fungal ball in an elderly man complaining of chronic headache, progressive unilateral nasal blockage and post-nasal drip. The role of Penicillium in a fungal ball and management are further discussed.
