title: Thoracolumbar spine subdural hematoma as a result of nonaccidental trauma in a 4-month-old infant.
abstract: The authors describe the previously unreported occurrence of thoracolumbar subdural hematoma (SDH) resulting from nonaccidental trauma and emphasize the need for a complete and thorough neurological, physical, and radiological examination in all cases of suspected nonaccidental trauma. A 4-month-old male infant presented to the authors' Level 1 pediatric trauma center in respiratory arrest. According to the family, he had been previously healthy with a 1-day history of fussiness and irritability. While with one of the parents, the patient was noted to be apneic and had been shaken in 2 separate episodes in an attempt to stimulate respiration. Emergency services personnel intubated the child's trachea and transported him to the hospital. On arrival in the emergency department, the child was unresponsive and exhibited signs of myelopathy. A CT scan of his head demonstrated SDH and subarachnoid hemorrhage. Magnetic resonance imaging of the spine demonstrated an SDH dorsal to the spinal cord with some mass effect on the conus medullaris and descending nerve roots. The patient underwent emergency T-12 to L-3 laminotomies, evacuation of the hematoma, and laminoplasty. The rigid nature of the rib cage provides a point of fixation around which the thoracolumbar spine can hyperflex and hyperextend when shaken, resulting in severe injury to the bony, vascular, and neural elements of the spine.
