A case of giant cell arteritis with jaw claudication and trismus treated with early steroid therapy. Issue 3 (May 2020) - Kitamura, Tomohisa
Abstract: Giant cell arteritis (GCA) is a granulomatosis accompanied by angiitis that affects medium- and large-sized arteries. We present a case of GCA in a patient who presented with jaw claudication and occlusal pain. A 78-year-old man visited our department with left-sided facial pain associated with mastication. He also reported spontaneous left-sided facial pain and diminished vision. Based on his age, his new-onset left-sided headache, and a high erythrocyte sedimentation rate, he was diagnosed with GCA with immediate initiation of prednisolone (PSL) therapy. His fever subsided the following day. A temporal artery biopsy (TAB) was performed 7 days after hospitalization and showed a false-negative result. His left-sided facial pain and headache subsided 29 days after therapy initiation. He was diagnosed with bladder cancer 3 months later, and we considered a probable association between his left-sided facial pain and paraneoplastic syndrome. GCA was diagnosed clinically based on the American College of Rheumatology criteria. Prompt PSL treatment is warranted without waiting for TAB results to avoid visual loss or other complications in this patient population.
