Presentation and management of bronchogenic cysts in the adult

Abstract

Bronchogenic cysts are congenital anomalies of the bronchial tree that are often asymptomatic at presentation in adults. Management of asymptomatic bronchogenic cyst in this population remains controversial. Eighteen patients with bronchogenic cysts were treated at our institution since 1975. At initial presentation, 10 patients (56 percent) were asymptomatic and 8 (44 percent) were symptomatic. Cough and pain were the most frequent symptoms. Two patients presented with potentially serious complications, one with respiratory distress from airway compression and the other with infection and airway fistulae. Chest radiographs were abnormal but nondiagnostic in 17 out of 18 (94 percent) patients. Chest computerized tomography (CT) scans were abnormal in eight of eight (100 percent) patients, but they confirmed the benign cystic nature in only five of eight (62.5 percent). Overall, considering the use of all imaging modalities and clinical suspicion, bronchogenic cyst was considered in the preoperative differential diagnosis in only 11 of 18 (61 percent) patients. Fifteen of 18 cysts were resected initially. Three of the asymptomatic patients who were followed up initially ultimately required resection because of the development of symptoms. A trend toward increased postoperative complications was noted in patients who were symptomatic at the time of surgery (27 percent vs 14 percent). In conclusion, adult patients with asymptomatic bronchogenic cyst may develop symptoms over time. Symptoms in adults can sometimes be potentially serious. Since a confident preoperative diagnosis is not always possible and because surgical complications may be more common in the symptomatic patient, we recommend surgical resection of all suspected bronchogenic cysts in operable candidates.
