Large spontaneous lung hernia-a case report

Intercostal lung hernias can be results of trauma or surgery. True spontaneous lung hernias thought to be a result of sudden acute increase in intrathoracic pressures are extremely rare. Only 51 cases have been reported in literature over the past four-and-half decades. We report a case of spontaneous chest wall posterior-lateral lung herniation that developed in a 73-year-old following severe coughing and straining during an episode of lower respiratory tract infection. Herein we present the unusual findings in the case and outline the pathophysiology of the problem and management options available.
