- We present a case of fatal cervical discoligamentous hyperextension injury without fracture. Postmortem computed tomography (PMCT) and postmortem magnetic resonance imaging (PMMRI) disclosed cervical instability and spinal cord injury in the absence of fracture, which was confirmed by autopsy. Cervical discoligamentous injury without fracture may be unnoticeable on PMCT because signs of cervical misalignment change depending on the posture of the neck at the time of postmortem imaging. Because of its greater sensitivity for soft tissue injury, PMMRI is especially useful for detecting pathological changes in cases of death due to cervical discoligamentous injury. In this paper, findings on postmortem imaging for this injury are described in detail and correlated with findings on autopsy.
