Identification of an unknown corpse by means of computed tomography (CT) of the lumbar spine.

For the first time, a case is described in which an unknown corpse is identified by the comparison of antemortem and postmortem computed tomographic (CT) images. A posterolat- eral disc herniation at L5-S1 on the right side, Schmorl's nodes and a lucency in the ilium were found in identical locations in each case. Additionally there were characteristic morphological similarities in the vertebral bodies, spinous processes, transverse processes and neural arches. In CT identification, as in conventional radiographic identification, one must try to reproduce comparable scanning conditions and images because apparent differences in the roentgenological morphology can occur as a result of different gantry angles or slice thicknesses.
