35-year-old female patient with left histologically proven orbital IOP. a. Axial T2W image shows a plaque-like hypointense extraconal lesion (arrowhead), adjacent to the lateral rectus muscle. Lymphoma was considered as an imaging differential. b. ADC map of the orbits of the same patient shows an ADC value of 1.1 × 10−3 mm2/s (arrowhead), which is higher than the ADC value expected for lymphoma. c. Axial PET/CT image of the same patient shows high FDG uptake within the lesion (arrow) (SUVmean = 5, SUVmax = 6) mimicking lymphoma
