Dyke-Davidoff-Masson syndrome

Case contributed by A.Prof Frank Gaillard

Two selected images from a CT demonstrate right cerebral hemiatrophy and enlargement of the right frontal sinus.

Case Discussion

Dyke-Davidoff-Masson syndrome was initially described as changes in the skull seen on skull X-ray in patients with cerebral hemiatrophy, but is now applied more broadly to cross-sectional imaging also. It is characterized by:

  • thickening of the skull vault (compensatory)
  • enlargement of the frontal sinus (also ethmoidal and mastoid air-cells)
  • elevation of the petrous ridge
  • ipsilateral falcine displacement
