Magnetic Resonance Imaging in Fungal Sinusitis With Emphasis on Additional Sequences: Diffusion Weighted Imaging and Susceptibility Weighted Imaging

Abstract

MRI, specially contrast enhanced MRI study, is the modality of choice in the diagnosis of non-invasive fungal sinusitis when CT is not conclusive, as well as invasive fungal sinusitis with its intraorbital, intracranial and soft tissue extensions. As well as to add DWI and SWI to all cases of suspected fungal sinusitis as they both can help in the diagnosis of fungal sinusitis and detection of complications.This study included 31 patients (11 males, 20 females with mean age 51) suffering from fungal sinusitis who are presented to Alexandria main university hospital, 5 patients had non-invasive types (3 cases had fungal ball and 2 cases had Allergic fungal sinusitis), 26 cases of invasive fungal sinusitis (5 cases of early invasive fungal sinusitis and 21 cases of late invasive fungal sinusitis), All the patients were subjected to:•Full history taking •Thorough Clinical examination by ENT physicians.•MRI study including:-Conventional T1W and T2W -Susceptibility weighted image -Diffusion weighted image Postcontrast T1W fat sat image whenever it is possible to give intravenous gadolinium
