Dyke-Davidoff-Masson Syndrome (DDMS) occurs when there is damage to one lobe of the brain resulting in hemiatrophy.
Conditions associated with Dyke-Davidoff-Masson Syndrome (DDMS):
(1) vascular occlusion of the middle cerebral artery in utero
(2) congenital malformation
(3) perinatal hypoxia
(4) intra-uterine infection
(5) intra-cerebral infection during infancy or childhood
(6) head trauma during infancy or childhood
(7) brain tumor
(8) intracerebral hemorrhage during infancy or childhood
Acquired DDMS is associated with:
(1) prominent sulci and
(2) less prounounced compensatory skull changes (if event is after 2 years of age)
as compared to DDMS associated with prenatal injury.
