The CHA of childhood or Dyke-Davidoff-Masson syndrome, is originated by intrauterine or perinatal insults that affect the perfusion of a single cerebral hemisphere, manifesting clinically by variable mental retardation, refractory epilepsy, facial asymmetry, hemiplegia/hemiparesis or abnormal movements of the contralateral extremities and by imaging studies, loss of volume in one cerebral hemisphere and ipsilateral compensatory cranial changes such as skull vault thickening, elevation of the orbital roof and petreous ridge, also hyperpneumatization of the frontal sinus and mastoid cells.
