Abstract
Intercostal lung herniation is defined as a protrusion of the lung parenchyma through a defect in the intercostal muscles between adjacent ribs. The authors report a case of intercostal pulmonary hernia in a 45-year-old male patient, with smoking habit (30 packs-year), presented to the emergency department with dyspnea. He had the history of pulmonary emphysema complicated with a total right pneumothorax in 2015 treated by mini-thoracotomy with bullectomy and pleural abrasion. In 2019, he was admitted to hospital for left chest pain. The computed tomography (CT) scan of the chest revealed a bilateral emphysema with intercostal lung hernia through the fourth intercostal space the patient underwent, a left thoracotomy with repair of the intercostal muscle defect. He was discharged from hospital free of complications.
