FIGURE 27.1 Identification by comparison of antemortem and postmortem CT. The antemortem study is on the viewer’s left in every instance. (A) Posterolateral disc herniation at L5-S1. (B) Small Schmorl’s node in the inferior end-plate of L4. (C) Peculiar thickening of the right transverse process of L4. (D) Shows identical lucencies in the left ilium at the sacroiliac joint.

FIGURE 27.2(A) Topogram, or scout film, of an antemortem CT study of an elderly female with hyperostosis interna frontalis is easily matched with (B) a routine skull film showing the same condition and an identical configuration of the sella and other anatomy of the skull.
