Traumatic induced total myelomalacia of the cervical spinal cord associated with a space-occupying subdural hematoma

We report the case of a 20-year-old male driver who suffered from a trauma to the cervical vertebral column in a head-on collision with a tree. The injuries included subluxation of the 2nd and 3rd cervical vertebrae and fracture of the odontoid process of the axis with ventrally directed displacement of the proximal fragment and dorsally directed displacement of the distal fragment. Already at admission to hospital a space-occupying spinal subdural hematoma was diagnosed. Clinically, paraplegia was diagnosed with progressive loss of consciousness. Pneumonia led to death 40 days after the accident. Autopsy disclosed a total myelomalacia of the cervical spinal cord obviously resulting from an ischemia caused by a traumatic lesion of the dorsal truncus arteriosus spinalis as well as a compression by the spinal subdural hematoma.
