Spinal cord infarction in meningitis: polygenic risk factors.

We report a male with spinal cord infarction and tetraplegia after Streptococcus pneumoniae meningitis. He was subsequently found to have both a Chiari I malformation and factor V Leiden mutation. A literature search was conducted to identify previously reported cases of pediatric spinal cord infarction associated with acute bacterial meningitis, anatomic brain anomalies, and hypercoagulability disorders. This article is the first report of spinal cord infarction in a child with hypercoagulability disorder and structural brain anomaly in the setting of acute bacterial meningitis. The confluence of infection, inflammation, localized pressure, and predisposition to hypercoagulability produced unique conditions resulting in infarction of the cervical spine. This report emphasizes the polygenic nature of the expression of spinal cord infarction.
