Post-traumatic Pneumatocele in the Inferior Pulmonary Ligament

Abstract

Pneumatocele localized to the inferior pulmonary ligament is an uncommon sequel of blunt chest trauma. Three such cases are reported and the characteristic location and appearance of the pneumatocele, as well as its benign course, are discussed. A similar radiographic appearance was produced in cadavers by injecting air into the inferior pulmonary ligament.
