Cerebrospinal fluid (CSF) oculorrhea is very rare after traumatic head injury. CSF fistula can cause hazardous complications including infection of central nervous system(CNS). A 40-year-old male visited with epiphora occurring every morning. He underwent traumatic head injury about a year and a half ago. Intrathecal Gadolinium-Enhanced Magnetic Resonance (MR) Cisternography was performed to diagnose his CSF oculorrhea. The delayed CSF oculorrhea was successfully treatment with continuous lumbar drainage. This case report discusses the diagnosis and treatment of the very rare case of the delayed CSF oculorrhea after mild blunt traumatic head injury.
