Childhood lumbosacral plexus neuropathy

Primary lumbosacral plexus neuropathy without underlying disease is a well-defined syndrome characterized by pain, weakness, and atrophy in the distribution of the lumbosacral plexus. It generally affects adults and rarely occurs in children. We report 2 children with primary lumbosacral plexus neuropathy evaluated at our institution and review the literature. This syndrome, despite initially severe symptoms, appears to be benign with a favorable prognosis in children.
