Post-traumatic haemorrhage in corpus callosum: a case study of disconnection syndrome.

This paper reports the case of a 16-year-old man who had sustained a traumatic head injury. Neuroradiological examinations showed haemorrhagic lesion in corpus callosum. The patient initially demonstrated several symptoms of disconnection syndrome; however, these clinical signs later resolved in subtle dysfunctions that could be evidenced only by statistical analyses of performances to specific tests. It is thus suggested that comparable cases may be undetected by standard examination procedures.
