MRI findings in diabetic female patient, 65 years old, presented mainly with Rt. eye proptosis, with decreased in vision, following COVID-19. A Axial T2W as well as B Axial and C Coronal post-contrast fat-saturated T1WI showed bilateral ethmoidal sinusitis (asterisks), with extension of the inflammatory process to the Rt. orbit, resulting in proptosis of Rt. eye globe, with posterior globe tenting, as well as Rt. periorbital and eyelids edema. There is retro-orbital fat stranding (White arrows) and thickened and enhanced Rt. extra-ocular muscles (red arrows). Rt. optic nerve showed restricted diffusion on DW images (Yellow arrows) at b-value 1000 (D) and apparent diffusion coefficient (ADC) map (E) in keeping with Rt. optic nerve infarction
