case_images: A 40-year-old man was referred to our ophthalmology clinic for left temporal and retroauricular pain, left-sided eyelid edema and ptosis (fig. 1a). Magnetic resonance imaging (MRI) of the brain and orbit showed contrast enhancement ranging from the tip of the left orbit to the cavernous sinus, the lacrimal gland and the superior rectus muscle (fig. 1b). Histological examination revealed mixed lymphocyte infiltration with CD20-positive B cells and CD5-positive T cells (fig. 1c, d) and no evidence of increased IgG4-positive plasma cells.
