Magnetic resonance imaging depiction of acquired Dyke–Davidoff–Masson syndrome with crossed cerebro-cerebellar diaschisis: Report of two cases

Acquired Dyke–Davidoff–Masson syndrome, also known as hemispheric atrophy, is characterized by loss of volume of one cerebral hemisphere from an insult in early life. Crossed cerebellar diaschisis refers to dysfunction/atrophy of cerebellar hemisphere which is secondary to contralateral supratentorial insult. We describe magnetic resonance imaging findings in two cases of acquired Dyke–Davidoff–Masson syndrome with crossed cerebro-cerebellar diaschisis.
