Bronchiectasis is classically defined as irreversible bronchial dilatation that represents the sequelae of chronic airway inflammation and is permanent, reflecting the presence of bronchiectasis. It is increasingly being recognized with the wider availability of high-resolution computed tomography. In contrast to adults, children with noncystic fibrosis bronchiectasis may have resolution or significant improvement in bronchial dilatation. We report a case of reversible bronchial dilatation in an adult as evidenced by high-resolution computed tomography, which demonstrates that, although quite rare in adults, spontaneous resolution may occur.
