RT Journal Article SR Electronic T1 Dandy Walker malformation and hypertrophic cardiomyopathy. Unusual fatal association JF Neurosciences Journal JO Neurosciences (Riyadh) FD Prince Sultan Military Medical City SP 368 OP 370 VO 14 IS 4 A1 Kurdi, Maher E. A1 Chamsi-Pasha, Mohammed A.

YR 2009 UL http://nsj.org.sa/content/14/4/368.abstract AB Dandy Walker malformation (DWM) is a rare congenital brain anomaly characterized by cystic dilation of the fourth ventricle and hypoplasia of the cerebellar vermis. Other extracranial anomalies can be associated, including cardiac defects. We report a rare patient with DWM associated with progressive heart failure secondary to hypertrophic cardiomyopathy. He was diagnosed at 2 months of age and died 5 months later. We conclude that hypertrophic cardiomyopathy can be associated with DWM with poor prognosis. A careful cardiac evaluation is needed in all infants with DWM for early recognition of such potentially serious associated cardiac malformations.
