A previously healthy 25-yr-old female developed flaccid areflexic
tetraplegia, with intact cranial nerve function, 36 h after the diagnosis
of bacterial meningitis. Polymerase chain reaction studies of cerebrospinal
fluid and blood were positive for Neisseria meningitidis, serogroup B.
Magnetic resonance of the cervicothoracic spine revealed increased signal
intensity and expansion in the lower medulla, upper cervical cord and
cerebellar tonsils. Neurosurgical consultation recommended
hyperventilation, dexamethasone and regular mannitol therapy rather than
decompressive intervention. The clinical course over the following 12 days
was complicated by the development of progressive central nervous and
multisystem organ failure with disseminated intravascular coagulopathy.
Autopsy revealed cerebral oedema with cystic infarction extending from the
medulla to the upper cervical cord and cerebellar tonsils. Flaccid
areflexic tetraplegia with spinal cord infarction has not been reported
following bacterial infection in an adult. The clinical implications would
suggest complete central nervous system evaluation of patients recovering
from meningococcal meningitis, since spinal cord lesions, although
uncommon, do occur. In those very rare situations where a patient develops
significant peripheral neurological deficits, urgent magnetic resonance
imaging is warranted, to rule out an infective focus or an underlying
anatomical anomaly.
