Guillain-Barré syndrome after brachial plexus trauma: case report

the guilllain-barré syndrome (gbs) is an acute predominantly demyelinating polyneuropathy. in many cases gbs is preceding by infection, immunization, surgery or trauma. although there are a few reports of gbs after head trauma, there is no report of this syndrome after brachial plexus injury. we report on a 51 years-old man who presented gbs fifteen days after a brachial plexus trauma. the polineuropathy resolved completely in a few weeks. we believe that gbs was triggered by the trauma that evoked an immune mediated disorder producing inflammation and demyelination of the peripheral nerves.
