title: Lumbosacral magnetic root stimulation in lumbar plexopathy.
abstract: We report a 76-yr-old man with left femoral nerve distribution weakness resulting from a nontraumatic retroperitoneal hematoma associated with coumadin anticoagulation. Although electric root stimulation was relatively contraindicated, magnetic lumbosacral root stimulation identified a proximal conduction block allowing more extensive assessment of the nerve damage. To our knowledge, this is the first report of magnetic root stimulation in assessment of lumbosacral plexus dysfunction in retroperitoneal hematoma.
