LUMBOSACRAL PLEXUS NEUROPATHY - A CASE-REPORT AND REVIEW OF THE LITERATURE

Lumbosacral plexus neuropathy (LSPN) is an idiopathic clinical syndrom e characterized by the sudden onset of neuropathic pain, followed by w eakness and sometimes sensory disturbances in the distribution of the lumbosacral plexus. Prognosis is usually favourable, although complete recovery may take several months to years. LSPN is the lumbosacral co unterpart of the neuralgic amyotrophy syndrome (idiopathic brachial pl exus neuropathy). We present a patient who initially was misdiagnosed with a radicular syndrome, but illustrates the typical signs and sympt oms of LSPN. We also give clinical and electromyographical criteria fo r the diagnosis of LSPN and review the literature. (C) 1997 Elsevier S cience B.V.
