Diagnostics of incomplete Brown-Sequard syndrome caused by meningococcal myelitis.

We are reviewing a 20-year old girl with the history of acute meningococcal sepsa with meningitis and thoracic myelitis resulting from an early embolia into the spinal cord, which is a very rare complication of meningococcemia. The ipsilateral loss of sensation indicates lesion of the posterior ascendent fiber tracts in the spinal cord, witout contralateral motoricity deficite, this indicating the incomplete Brown-Sequard syndrome. Somatosensory-evoked potentials (SSEP) of the n. tibialis show milder impediments of conductivity by the thoracic segment at left. Magnetic resonance (MRI) of the thoracic spine shows lesion of the posterior ascendent fiber tracts (Fig. 2, Ref. 17).
