Abstract
Two recent patients with bronchogenic cysts, presenting in an atypical manner, stimulated our review of this subject. Twenty patients with bronchogenic cysts have been treated at the Boston Floating Hospital over the past 20 yr. Of these patients, 19 out of 20 were symptomatic, the most common symptom being fever (6 out of 20). Half of our patients had no respiratory symptoms but only one was found to have an asymptomatic mass on chest x-ray. The majority of theses cysts were found within the pulmonary parenchyma, the right lung being affected three times more commonly than the left. These facts are at odds with the reports in the literature. Three were found in the neck. Bronchogenic cysts are generally thought to be small, solitary, and limited in area. However, a significant number in our series (8 out of 20) were large, multiple or multicystic, and involved segments, lobes, multiple lobes, and, on one occasion, an entire lung. The correct pre-operative diagnosis was made in only 30% of the cases. The fact that the diagnosis was often missed led to long delays in treatment resulting in recurrent infectious complications and repeated hospitalizations. The most common cause of error in diagnosis was failure to follow a pneumonia to complete resolution. Despite the frequent delays in diagnosis, surgical treatment was curative in all patients.
