Traumatic Chiasmal Syndrome: A Midline Axonal Injury

Abstract

We report a 26-year-old man who developed cerebrospinal fluid (CSF) rhinorrhoea and complete bitemporal hemianopia after having sustained a blunt frontal region trauma. The chronology of midline frontal trauma and CSF rhinorrhoea, followed days later by transient diabetes insipidus and discovery of a bitemporal visual field loss, makes up a unique syndrome and must be evaluated for. Mechanism of such injuries, their pertinent complications, and review of literature are herein discussed.

• Bitemporal hemianopia
• blunt frontal region trauma
• midline axonal injury
• traumatic chiasmal syndrome
