FIGUEIREDO, Sandra et al. Occupational (?) constrictive bronchiolitis with normal physical, functional and image findings. Rev Port Pneumol [online]. 2009, vol.15, n.4, pp. 729-732. ISSN 0873-2159.
Constrictive bronchiolitis is characterized by alterations in the walls of membranous and respiratory bronchioles. These changes lead to concentric narrowing or complete obliteration of the airway lumen. Suspicion of possible bronchiolar disorders may arise from clinical, funcional, and radiologic findings. However, constrictive bronchiolitis may be present even with normal physical, functional and image findings, which turns the diagnosis difficult. A high index of suspicion is necessary to justify invasive tests that lead to pulmonary biopsy. In this report, we describe a patient with cough and dyspnoea, with normal physical, functional and image findings, whose work-up leaded to the diagnosis of constrictive bronchiolitis
