Incudomalleolar dysarticulation

Case contributed by Assoc Prof Frank Gaillard

The head of malleus in the attic on the right is seen in isolation; the incus in not present (on a lower slice, not shown). This is in keeping with disarticulation of the incudomalleolar joint. 

Case Discussion

The articulation of the incus and malleus should appear as an ice-cream ball on an ice-cream cone on axial images and should be check area on all scans through the region, especially if head trauma and base of skull fractures are present.
