Dyke-Davidoff-Masson Syndrome: Time to Revisit Case Series

We read a case report by Manghera et al (JAPI, Vol 62 page No. 76-67), which was in response to an earlier case report by Ola et al.1 Here we would like to share our experience and views as under- The authors in the correspondence have said that crossed cerebellar atrophy is an unusual and rare finding. We in our study of 28 patients of DDMS, have found cerebellar atrophy in nine patients along with cerebral atrophy.2 Out of nine patients with cerebellar atrophy three patients had diffuse bilateral atrophy, only one patient had unilateral cerebellar atrophy which was controlateral to left cerebral hemiatrophy (CHA). This is similar to the findings of the authors and the patho-physiology quoted by authors is worth appreciation. Other parenchymal changes observed in our study were cerebral peduncle atrophy in three patients, and thalamic atrophy with lentiform nucleus hypoplasia in 11 patients. Seven cases of CHA were associated with ipsilateral large schizencephalic cleft with absence of the septum pellucidum whereas two had porencephaly. Five patients had left-sided hippocampal sclerosis (HS), four were concordant and one was discordant.
