Bipolaris australiensis in a Spanish patient with allergic chronic sinusitis

Allergic fungal sinusitis is a disease that results from hypersensitivity reaction of the host against fungi colonizing the paranasal sinuses. A 36 years old Spanish man with no history of travel abroad had a history of asthma, nasal polyps, allergic rhinitis and a chronic sinusitis with nasal congestion and headaches. Computed tomography showed pansinusitis and opacification of the paranasal sinuses. A pure culture of Bipolaris australiensis was grown from sinus tissues. Infections caused by Bipolaris spp. and treatment regimes are discussed.
