[Isolated prolonged cough caused by Horton's disease]

Abstract

Pulmonary involvement is very rare in giant cell arteritis. The sign that is most often encountered seems to be dry cough which can remain, for a long time, the sole manifestation of this disease. We report a case of giant cell arteritis in a 66 year old woman that expressed for only symptom a dry cough during one year. A rapid regression of clinical symptoms and radiologic signs have been observed with steroid therapy. Presence of isolated cough along with biological marks of inflammation in a elderly patient should lead to temporal biopsy when no other evidence cause has been found.
