[Bronchectasis in Horton's disease: fortuitous association?].

Respiratory manifestations in Horton's disease are uncommon. We report the case of 63 year-old man with Horton disease diagnosed 2 months before, who was hospitalised for fever, deterioration in general health, cough and hemoptysis. Chest X-ray showed an infiltrate in the right upper lobe and bilateral cystic opacities predominant on basal suggesting bronchectasis who was confirmed secondary in CT-scan. Even though cortico sensible clinical manifestations and radiologic infiltrate were previously described in Horton's disease, association with bronchectasis was never been reported in literature and her etio pathogenic mechanism must be clarified.
