Lung herniation is described as the protrusion of lung tissue and pleura out of the thoracic cavity through an abnormal gap in the chest wall.We present a case with a rare lateral lung herniation.The patient was taken for urgent surgery and an anterolateral thoracotomy was carried out.Pursuant to rib and lung parenchyma repair, the herniation defect was closed without a prosthetic graft.The patient was discharged on the postoperative fifth day with full recovery.Although there is a lack of consensus on the timing of surgery, we are of the opinion that in blunt thorax trauma-induced symptomatic lung hernias, operating on the patient is appropriate as soon as a diagnosis is established should be advised.
