The major pulmonary finding in CF is bronchiectasis, which is an almost universal feature of this disease. It may be the sole feature of CF in adults or those with genetic variations of the disease. Bronchiectasis associated with CF is believed to occur secondary to mucous plugging of proximal airways and chronic pulmonary infection, especially with mucoid P aeruginosa. [33]
