Bronchogenic cysts are congenital anomalies of the bronchial tree that
are often asymptomatic at presentation in adults. Management of asymp
tomatic bronchogenic cyst in this population remains controversial. Ei
ghteen patients with bronchogenic cysts were treated at our institutio
n since 1975. At initial presentation, 10 patients (56 percent) were a
symptomatic and 8 (44 percent) were symptomatic. Cough and pain were t
he most frequent symptoms. Two patients presented with potentially ser
ious complications, one with respiratory distress from airway compress
ion and the other with infection and airway fistulae. Chest radiograph
s were abnormal but nondiagnostic in 17 out of 18 (94 percent) patient
s. Chest computerized tomography (CT) scans were abnormal in eight of
eight (100 percent) patients, but they confirmed the benign cystic nat
ure in only five of eight (62.5 percent). Overall, considering the use
of all imaging modalities and clinical suspicion, bronchogenic cyst w
as 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 ul
timately required resection because of the development of symptoms. A
trend toward increased postoperative complications was noted in patien
ts who were symptomatic at the time of surgery (27 percent vs 14 perce
nt). In conclusion, adult patients with asymptomatic bronchogenic cyst
may develop symptoms over time. Symptoms in adults can sometimes be p
otentially serious. Since a confident preoperative diagnosis is not al
ways possible and because surgical complications may be more common in
the symptomatic patient, we recommend surgical resection of all suspe
cted bronchogenic cysts in operable candidates.
