[Idiopathic lumbosacral plexopathy].

[neuralgic amyotrophy]

Lumbosacral plexopathy is the equivalent in the lower limbs of neuralgic amyotrophy (also known as Parsonage-Turner syndrome ) in the upper limbs . It is well-known in patients with diabetes mellitus , when it is known as Bruns -Garland syndrome .We report the case of a 47 -year -old woman who developed a unilateral neuropathy of the leg , neither radicular nor truncal in origin . The slow continuous improvement was not affected by any of the treatments administered .Lumbosacral plexopathy is characterized by intense pain in one or both legs , associated with motor and sensory deficits . Recovery is usually slow (6 to 36 months ) and often incomplete . The electrodiagnostic examination shows important acute motor and sensory axonal loss , characterized by denervation and low -amplitude sensory action potential . Treatment generally combines analgesics with narcotic agents , neuropathic pain medication , short -term corticosteroids , and rehabilitation . In the most severe cases , long -term corticosteroids and other immunosuppressive agents may be required . This diagnosis can not be reached until all other radicular , plexal and truncal origins have been ruled out .
