ABSTRACT
Introduction : Fungal sinusitis was once considered a rare disorder but is now reported with increasing frequency throughout the world. Fungal chest infection is relatively considered common. The classification of fungal sinusitis has evolved in the past two decades, and this entity is now thought to comprise five subtypes. Acute invasive fungal sinusitis, chronic invasive fungal sinusitis and chronic granulomatous invasive fungal sinusitis made the invasive group, whereas non-invasive fungal infection is composed of allergic fungal sinusitis and fungus ball (fungal mycetoma). Objective : The five subtypes of sinusitis described above are distinct entities with different clinical and radiologic features. The treatment strategies for the subtypes are also different, as are their prognosis. We aim to clearly delineate the radiologic features of culturally proven fungal cases so as to direct the clinician towards expeditious diagnosis and necessary treatment. Methodology : 40 culturally positive patients with the spectrums of different manifestations were studied and recorded. They were followed up for one month. Conclusion : An understanding of the different types of fungal sinusitis and knowledge of their particular radiologic features allowed the radiologist to play a crucial role in alerting the clinician to use appropriate diagnostic techniques for confirmation. Prompt diagnosis and initiation of appropriate therapy avoided a protracted or fatal outcome.
