allergic fungal sinusitis (afs) has been recognized as an important cause of chronic sinusitis commonly caused by aspergillus spp. and various dematiaceous fungi like bipolaris, alternaria, curvalaria, and etc. ulocladium botrytis is a non pathogenic environmental dematiaceous fungi, which has been recently described as a human pathogen. ulocladium has never been associated with allergic fungal...

BACKGROUND AND PURPOSE It is important to differentiate fungal from nonfungal sinusitis in order to determine the optimal treatment for chronic sinusitis. The purpose of this study was to describe the CT findings of calcifications in chronic fungal and nonfungal maxillary sinusitis. METHODS Five hundred ten patients with pathologically proved chronic maxillary sinusitis were studied with unen...

Background and Purpose: Chronic granulomatous disease (CGD) is an inherited disorder of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex. This disorder results in recurrent life-threatening bacterial and fungal infections. Aspergillus species are the most common fungal infections in these patients. Case Report: Herein, we present a case of fungal infection in a girl wi...

fungal involvement of the paranasal sinuses is frequently observed in the immunocompromised host and it can become lifethreatening if it is not diagnosed. definitive diagnosis is made by tissue biopsy and culture. in this study biopsy materials of maxillary, ethmoidal and frontal sinuses of 60 patients with clinical manifestation of sinusitis and no response to medical therapy were assessed by ...

Allergic fungal sinusitis (AFS) is a non-invasive form of allergic sinusitis, resulting from the IgE-mediated hypersensitivity reaction to fungal antigen in atopic individuals. It was first described in 1983 by Katzenstein.1 It usually follows a slow, non-aggressive course, and a wide variety of fungal agents have been implicated, with the vast majority belonging to the Dematiaceae family, such...

Fungi have emerged as important etiological agents for chronic sinusitis. Invasive aspergillosis has been reported in immunocompromised individuals or diabetics; however, it is uncommonly seen in immunocompetent patients. Definitive diagnosis of these lesions is based on histological examination and fungal culture. We report two cases of invasive maxillary lesions in immunocompetent patients, c...
