Dyke–Davidoff–Masson Syndrome – A Case Series

Dyke–Davidoff–Masson syndrome (DDMS) refers to variable degrees of atrophy of one cerebral hemisphere, resulting from brain injury in intrauterine or early years of life. Clinical features of this rare syndrome include varying degrees of contralateral hemiplegia, facial asymmetry, seizures, and mental retardation. Specific neuroimaging findings include unilateral brain volume loss, ventriculomegaly, and compensatory bone hypertrophy. In addition to this, calvarial thickening and hyperpneumatization of frontal sinuses may occur. We hereby report three cases of this syndrome, with varied clinical and radiographic features, to highlight the wide spectrum of this syndrome.
