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.
