Bronchial diverticulosis: a case report and literature review

Diverticulosis bronquial: presentación de un caso y revisión de la literatura

Bronchial diverticula are rare, benign entities characterized by invaginations or blind sacs of the airway wall. Its first descriptions date back to 1838, by Rokitansky, and begin as submicroscopic depressions and dilations of the bronchial gland ducts on the mucosal surface, which then fuse and herniate through bundles of smooth muscle cells. We present a case of a patient, in the fifth decade of life, followed by the Pneumology service since the age of 30, who reported early-onset asthma (from the first year of life), with the need for 30 hospitalizations throughout her life, approximately, due to recurrent asthmatic attacks. Diagnostic imaging showed nodules and micronodules, some forming budding trees in the middle lobe, and some bronchiectasis with mucoid impaction, as well as irregularities in the bronchial wall, which turned out to be multiple diffuse diverticula throughout the bronchial tree.
