title: Giant cell arteritis presenting as interstitial lung disease.
abstract: A 58-year-old woman had a clinical history compatible with polymyalgia rheumatica but with an unexplained interstitial lung disease. Evaluation, including biopsy specimens of temporal artery, lung, and gastrocnemius muscle, was consistent with giant cell arteritis. This case identifies giant cell arteritis as a cause of interstitial lung disease.
