Diaphragmatic paralysis is an uncommon cause of pulmonary dysfunction and can occur after traumatic phrenic nerve injury. Penetrating and blunt trauma to the neck is the most recognized mechanism of injury being stretching of the nerves very uncommon. We report a case of a 39-year-old man with bilateral diaphragmatic paralysis due to violent stretching of the phrenic nerves. Clinical features and diagnosis methods are also reviewed.
