[Lung herniation after a single cough].

We present the case of an overweight male patient with a lung hernia caused by a single massive coughing attack. The diagnosis could only be verified by CT-scans. Following a conservative therapeutic approach, surgical intervention was necessary. Lung hernias are easy to detect using radiological diagnostic. Standard X-ray examinations where a subcutaneous air mass can be seen have become, since the inauguration of computed tomography, second line tests. Large traumatic lung hernias should be treated surgically. Spontaneous and especially cervical hernias should be handled conservatively and only must be surgically treated when complications or a progression in size should be observed.
