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
