“…Morel–Lavallée described their classification in 1845 [1, 8, 9]. On the one hand, it distinguishes congenital pulmonary hernia (20%) from acquired (80%), on the other hand, it distinguishes them according to topography: cervical (17–35%), intercostal (65–83%), or diaphragmatic [3, 9]. Acquired hernias are traumatic, but some spontaneous cases have been reported among patients with some predisposing factors such as a chronic cough, chronic and obstructive bronchopulmonary diseases, neoplasia, chronic use of steroids, and Ehlers–Danlos syndrome [3, 6, 10, 11].…”
