Bronchogenic cysts

Bronchogenic cysts are relatively uncommon congenital lesions. They may be detected on routine radiography in asymptomatic patients or may present with various manifestations, some of which may be life-threatening. Age at diagnosis ranges from infancy to late adulthood, with asymptomatic lesions occurring more often in older children and adults. Cysts may be located in subcarinal, paratracheal, hilar, paraesophageal and intrapulmonary sites. The chest radiograph is the primary diagnostic study, with computed tomographic scans of the chest providing more definitive evaluation. Despite some controversy, surgery is considered the treatment of choice, even in the asymptomatic patient.
