Magnetic Resonance Imaging Prognostic Findings for Visual and Mortality Outcomes in Acute Invasive Fungal Rhinosinusitis


Extra-sinonasal involvement in AIFRS typically signals advanced infection with the facial soft tissues most commonly affected. The initial, pre-intervention MR imaging is prognostic for a poor visual acuity outcome when there is orbital apex and/or cerebral arterial involvement. Facial soft tissues, nasolacrimal drainage apparatus, and/or intracranial involvement is associated with increased mortality risk, while orbital soft tissue involvement is correlated with a reduced risk of mortality.
