[Post-traumatic idiopathic pneumopericardium and pneumoperitoneum].

One case of "idiopathic pneumoperitoneum" following closed thoraco abdominal injury, primitively associated with a pneumopericardium is reported. No etiology was discovered about these two aeric effusions. Also it was interesting to compare this experience with literature to know frequency of such association; physiopathologic mechanism responsible and management of the described other cases.
