Post-traumatic meningitis in children.

A retrospective survey over a 66-month period of children admitted with head injury who subsequently developed meningitis within the same period yielded six cases (five boys, one girl), giving an incidence of 0.38 per cent. Two of the six died, and four survived with no sequelae. Four cases occurred within the first week. One patient, who had received prophylactic antibiotics, developed Escherichia coli meningitis after 14 days and one had meningitis 2 years after the head injury. The most common organism was pneumococcus (four cases). Three patients had periorbital haematomas and none had cerebrospinal fluid leakage. Increasing drowsiness and fever were the most consistent features. Radiography of the skull was of little use in demonstrating fracture of the base of the skull. Two of the four surviving patients had craniotomy with successful dural repair.
