Summary

This case study reports a patient with complete callosal disconnection syndrome following severe head injury. This rare condition, involving the corpus callosum, may be frequently overlooked in traumatic brain injury assessments.

Area of Science:

  • Neuroscience
  • Neurology
  • Radiology

Background:

  • Traumatic brain injuries can cause damage to the corpus callosum.
  • Clinical signs of callosal disconnection are rarely observed after head injuries.

Observation:

  • A patient with a severe closed head injury presented with complete destruction of the corpus callosum, confirmed by MRI.
  • The patient also exhibited a severe memory disorder, potentially linked to fornix damage.

Findings:

  • This case represents the first reported instance of a complete callosal disconnection syndrome after head trauma.
  • Post-traumatic callosal disconnection may be underdiagnosed.

Implications:

  • This highlights the importance of recognizing callosal disconnection syndrome in head injury patients.

  • Further research is needed to understand the full spectrum and diagnostic criteria for post-traumatic callosal disconnection.
