Herniation of the lung is commonly caused by congenital rib abnormalities,
blunt trauma, or thoracic surgery. Spontaneous hernias are rarely described
in the literature. We report a case of a spontaneous intercostal pulmonary
hernia following a single cough. In addition, a review of the literature i
s presented which outlines the classification, causes, and incidence of lun
g hernias. Some reference is made to,possible methods of treatment.
