T1-weighted magnetic resonance images of the orbit with gadolinium infusion and fat suppression. (A) Coronal image taken at initial presentation showing a mass involving the right orbital space and extending into the ethmoidal sinus. The mass is displacing the globe. A small mass is also shown in the left orbital space. (B) Coronal image showing reduction of the pseudotumor 12 weeks after treatment.
