Paravertebral venous plexus distention (Batson's): an inciting etiologic agent in lumbar radiculopathy as observed by venous angiography.

Abstract

Can the paravertebral plexus of veins adjacent to the spinal nerve root within the narrow confines of the lateral neural canal be a collateral generator of radicular pain when no other evidence of spinal pathology is evident? A patient with complaints of intractable lumbar radiculopathy and an otherwise unremarkable clinical neuromusculoskeletal examination, as well as normal imaging and electrodiagnostic studies, is reviewed with special reference to symptomatic and paravertebral venous responses to both a Valsalva maneuver and dipyridamole infusion as imaged by magnetic venous angiography.
