Diaphragmatic paralysis in a patient with spinal cord infarction.

This report describes the rare case of a 72-year-old woman with spinal cord infarction who presented with persistent diaphragmatic paralysis. Her neurological examination showed tetraplegia, sensory loss to pain and thermal stimulations, and paradoxical abdominal movement. Chest X-ray and diaphragmatic fluoroscopy revealed absent diaphragmatic movement. A cervical magnetic resonance image showed bilateral anterior spinal cord lesions from the level of the second to the fifth cervical vertebrae. Diaphragmatic paralysis should be recognized as a clinical sign of cervical spinal cord infarction. Particular attention must be given to paradoxical abdominal movement during respiration in this disorder.
