A case of giant bronchocele is reported. This lesion is due to a mucus and pus filled dilatation of the bronchial tree proximal to a stenosis. The latter can be either congenital or acquired, or in the context of a diffuse bronchopathy, which can be responsible for a functional stenosis. Both plain radiography and computed tomography findings are diagnostic. The etiology of the abnormality however represents an important problem to be solved. Further, a thoractomy is often necessary, except in those case arising in the context of a diffuse bronchopathy, which usually resolve either spontaneously or following medical treatment.
