Idiopathic lumbosacral plexus neuropathy in two children.

Two children diagnosed as having idiopathic lumbosacral plexopathy are presented. Although an apparently rare condition, it is probably underdiagnosed since it is difficult to recognise. Before such a diagnosis, careful exclusion of compressive and infiltrative lesions of the spinal cord, cauda equina and lumbosacral plexus is of utmost importance.
