Temporal arteritis without histological changes

: A patient with severe giant cell arteritis with involvement of both eyes is presented. The symptoms were partly reversible by treatment with high doses of prednison. Three months previously (having symptoms of polymyalgia rheumatica) she had started treatment with a low dosage of prednison. Biopsies of both temporal arteries showed no signs of giant cell arteritis at that time, and the results of eye examinations were normal. The importance of follow-up on patients with symptoms of polymyalgia rheumatica, even if biopsies of the temporal arteries show no histological changes, is emphasised.
