title: Acute traumatic orbital cerebrospinal fluid cystocele mimicking orbital abscess.
abstract: Posttraumatic cranio-orbital cerebrospinal fluid (CSF) fistula is rare, occurring when there is a communication between orbit and subarachnoid space. This communication can be caused by orbital tumors with intracranial extension or can be a result of orbital surgery. Low suspicion for traumatic orbital CSF fistula can lead to delay in diagnosis, which increases the risk of meningitis. We report a cranio-orbital CSF cystocele and fistula that mimicked orbital cellulitis in a 3-year-old boy following an orbitocranial penetrating injury.
