The “pseudo-CT myelogram sign”: an aid to the diagnosis of underlying brain stem and spinal cord trauma in the presence of major craniocervical region injury on post-mortem CT

The PCMS is a novel description of a diagnostic finding, which if present in fatal craniocervical region trauma, is very sensitive for underlying spinal cord and brain stem injuries not ordinarily visible on PMCT. Its presence may also predict major osseous and/or ligamentous injuries in this region when anatomical displacement is not evident on PMCT.
