Abstract
Four patients are presented who had apparently anomalous vascular channels that were initially erroneously interpreted as vascular malformations. These vascular channels represent the normal venous drainage of a pachygyric cortex. The recognition of this finding as a manifestation of the underlying abnormal neuronal migration is important in order to avoid further intervention in these patients.
