“…Long et al highlighted a 16% incidence of giant cell arteritis (GCA) in scleritis and a couple of case reports highlight scleral inflammation as one of the initial symptoms in patients with Takayasu arteritis . Other diseases that can present with scleral inflammation and large vessel vasculitis are syphilis, tuberculosis, ankylosing spondylitis, Behçet's disease, rheumatoid arthritis (RA), granulomatosis with polyangiitis (Wegener's) (GPA), relapsing polychondritis, and Cogan's syndrome . Based on our patient's initial presentation of aortitis and scleritis, we included syphilis, tuberculosis, RA, GCA, GPA, Cogan's syndrome, and sarcoidosis in our differential diagnosis list.…”
