Abstract:
Introduction: Acute Invasive Fungal Rhinosinusitis (AIFRS) is a critical and life-threatening, very rapidly progressing infection caused by fungi. COVID-19 disease may be associated with fungal coinfections, especially post-steroid treatment, and severely impaired glycemic control. MRI plays a vital role in the early diagnosis and severity of the infection. The purpose of this study is to highlight the various spectrums of the imaging findings. Methods: This is a prospective study done during and following SARS-Coronavirus 2 COVID-19 infection in India from April 2021 to February 2022. Descriptive statistics was the statistical tool used in this study. Results: MRI of 32 patients showed mainly involvement of the paranasal sinuses (100% of patients), nasal cavity (56% of the patients), orbits (47% of the patients), premaxillary, retroantral & pterygopalatine fossa (56% of the patients), skull base (34 % of the patients) and intracranial spread (25% of the patients). A heterogeneous hypointense signal on T2WI and peripheral heterogeneous enhancement with central non-enhancing areas in 15 patients (47%), known as a black-turbinate sign. Among intracranial spread, six patients developed cavernous sinus thrombosis (19% of the patients ), and four developed vascular infarcts (12.5% of the patients). The perineural spread was seen in a single patient (3%).

Among intracranial spread, six patients developed cavernous sinus thrombosis (19% of the patients), and four developed vascular infarcts (12.5% of the patients). The perineural spread was seen in a single patient (3%). Conclusion: Contrast-enhanced MRI shows various spectrums of findings in AIFRS, which hence plays a very important role in further assessing the extent of involvement, guiding for treatment, and predicting possible complications.
