Asymptomatic congenital lung malformations

The arguments
Some authors recommend simple observation of patients with asymptomatic CCAM,41, 42, 43, 44, 45 sequestration46, 47, 48 or prenatally diagnosed “lung masses.”49 However, most authors favor surgical resection, at least for CCAM, intralobar sequestation and bronchogenic cysts.2, 3, 7, 15, 24, 29, 31, 39, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69 Finally, others recommend surgery for “significant” lesions but may observe smaller ones.26, 38 The arguments for
Indications for surgery
Asymptomatic congenital lobar emphysema may resolve and should be observed once underlying lesions are excluded. Bronchogenic cysts require resection. For sequestrations, it is clear that ELS may remain asymptomatic throughout life and may be found because of associated anomalies.3, 97 They may also regress spontaneously. The risk of malignancy appears low despite its frequent association with type 2 CCAM. The risk of infection is small in the absence of cysts or communication with the foregut
