© 2019 Elsevier Inc.Dyke-Davidoff-Masson syndrome (DDMS) was first described in 1933 as a clinical condition characterized by hemiatrophy, hyperpneumatization of paranasal sinuses, contralateral hemiparesis, facial asymmetry, seizures, and mental retardation.1 DDMS can be of 2 types: congenital and acquired. The congenital type can be caused by various conditions experienced during fetal or early childhood development, including ischemia, infarction, trauma, infections, and hemorrhage. The acquired type is mostly associated with hemorrhage, trauma, and infections experienced after 1 month of age. DDMS can manifest alone or can be accompanied by crossed cerebellar atrophy (CCA) which is a newly discovered radiological marker characterized by prominent cortical sulci and loss of cerebellar parenchyma. The congenital type of DDMS is known to be accompanied by ipsilateral cerebellar atrophy and the acquired type is known to be accompanied by contralateral cerebellar atrophy.2,3 Supratentorial events may lead to destruction in the cortico-ponto-cerebellar pathways, mostly in the contralateral side of the body (80%) due to decussation.4 In this report, we present 2 cases of DDMS accompanied by CCA to emphasize the possibility that the DDMS cases with severe intrauterine hemorrhage can be accompanied by contralateral CCA and migratory abnormalities rather than ipsilateral CCA and clinical survey.
