Surface lesions of corpus callosum

Summary Surface lesions of the corpus callosum, apparently hitherto unrecorded in the literature, are described. They were found in 17 cases among 168 consecutively examined brains. There was no correlation with clinical symptoms, or with general autopsy findings. Their morphology and relationship to neighboring structures suggest that they represent a form of physical trauma to the corpus callosum, but the exact mechanism of their production is not clear.Supported by US Public Health Grant NB6239 from the National Institute of Neurological Diseases and Blindness.
