접형동에 국한된 세균성 부비동염으로 오인된 알레르기성 진균성 부비동염 1예

Allergic fungal sinusitis is clinicopathologically defined as a benign, noninvasive variety of fungal infection. The most common involving sinus in the allergic fungal sinusitis is the maxillary sinus, followed by ethmoid sinus. On the other hand, sphenoid sinus is only occasionally affected. Solitary involvement of the sphenoid sinus is a relatively uncommon variety. Because of the anatomical location of the sphenoid sinus, the nasal airflow to be directed below the ostium, few bacteria or inhaled irritants are carried to the sinus. The most common presenting symptom is headache, which is not specific. Therefore once sphenoid sinus is encountered disease entity, it is often difficult to clinically establish the correct diagnosis. We present a case of allergic fungal sinusitis misdiagnosed as isolated bacterial sphenoiditis which were successfully treated with transnasal endoscopic sphenoidotomy followed by systemic and topical steroids and saline irrigation.
