Cerebrospinal fluid external leak after penetrating trauma in a neurologic intact infant patient: a case report.

Cranial cerebrospinal fluid (CSF) leak is an extremely rare complication of blunt head trauma causing skull fractures, especially fractures involving the skull base. We present the case of a 10-month-old male who received glass fragments on the midline and posterior tier of his anterior fontanelle producing a cranial cerebrospinal fluid leak without any skull fracture or symptoms. Neurologic exam was completely normal and a superficial stitch wound repair was performed. He was observed for 24 h, had no antibiotic, and left with a 1-week outpatient neurosurgical follow-up. The patient had no negative outcome. Cerebrospinal fluid leak should be included in the differential diagnosis of a head trauma in a patient with open fontanelles. No similar case was found in literature.
