RESUMEN
Giant Cell Arteritis (GCA) is a common systemic vasculitis that involves medium and large arteries, most frequently extracranial branches of the carotid artery. Prompt diagnosis and treatment is essential to prevent devastating complications, such as blindness, stroke and aortic aneurysm or dissection. Typical symptoms include headache, temporal artery tenderness and jaw claudication. On rare occasions patients present with complaints related to pulmonary involvement. These include interstitial infiltration, pulmonary nodules, pleural effusion and pulmonary haemorrhage. The authors report the case of a 74-year-old man who presented with symptoms compatible with GCA confirmed by temporal biopsy, and pulmonary nodules. These lesions were biopsied and histological exam confirmed features compatible with systemic vasculitis. The lesions resolved after two months of steroid treatment. This case shows that we should be aware of atypical GCA manifestations.
