Recurrent Streptococcus pneumoniae meningitis in a child with traumatic anterior cranial base defect.
Acute bacterial meningitis is a potentially life-threatening infection of the cranial and spinal leptomeninges. Recurrent episodes of meningitis are rarely seen, but when they occur, an extensive investigation has to be made to find out responsible factors. A single episode of acute meningitis may result from bacteriemia, but when followed by recurrent meningitis in pediatric patients, other possible routes of the bacteria invasion to the cerebrospinal fluid (CSF) should be considered. Patients with head injury have the highest risk of acquiring recurrent bacterial meningitis, followed by patients with a congenital anatomic lesion of the skull or duramater, such as meningomyelocele. The underlying cause is a transdural communication between the meningeal space and paranasal sinuses or skin. The first attack of meningitis may occur several weeks to 12 years after the head injury. In addition, recurrent bacterial meningitis may be due to disorders of the immune system, such as complement deficiency. We report a 14-year-old boy, who suffered from recurrent Streptococcus pneumoniae meningitis due to a well-defined defect at the ethmoid roof after a head trauma.
