Lumbosacral plexus neuropathy

Abstract

We describe 10 cases of lumbosacral plexus neuropathy in which no underlying condition was discovered on initial evaluation or on follow-up examination after an average of 6 years. The patients presented with pain and weakness. Recovery was delayed and often incomplete. When the lower plexus is involved, it may be confused with disk disease manifesting as "sciatica." This syndrome may be a counterpart to the well-described idiopathic brachial plexus neuropathy.

High-Resolution 3-T MR Neurography of the Lumbosacral Plexus

“…Systemic and inflammatory causes of lumbrosacral involvement include diabetes mellitus (diabetic amyotrophy), inflammatory neuritis (eg, Guillain-Barré syndrome), ischemic conditions, chronic inflammatory demyelinating polyneuropathy, hereditary neuropathies (eg, Charcot-Marie-Tooth disease), radiation neurop- athy, sarcoidosis, and connective tissue disorders (8,(26)(27)(28). In addition, a primary or idiopathic form of lumbrosacral plexopathy has been reported and is probably a result of an abnormal immunologic response; it is considered analogous to idiopathic brachial plexopathy (29,30). This form of lumbrosacral neuropathy is associated with a favorable outcome and spontaneous recovery, and it is diagnosed on the basis of the exclusion of other organic causes (31).…”

Bilateral lumbosacral plexopathy after mesenteric thrombosis

“…The second electromyography (14-2-97) Table 1. Demonstrated electrodiagnostic criteria for LSP 3 including denervation in muscles innervated by at least two lumbosacral segmental levels and involving at least two di erent peripheral nerves, without paraspinal involvement. Sensory nerve conduction showed absence of responses in all peripheral nerves in both legs.…”

“…The typical ®ndings in LSP include paraparesis with variable sensory loss, hypore¯exia, disesthaesia and preserved sphincter control. 1 Among other causes of LSP are: Idiopathic lumbosacral plexitis, 2 vasculitis, 3 infection, 4 hereditary liability to pressure, 5 hemorrhage, 6 trauma, 7 intra-arterial injections, 8 surgical conditions 9 and tumors. 10 …”

Lumbosacral Plexus Neuropathy-Idiopathic Sciatic Neuropathy: A Case Report

“…Lumbosakral pleksus nöropatisi ise 1981 yılında tanımlanmıştır (2,3). Bu klinik tablo bel ve bacak ağrısı, sonrasında günler ya da haftalar içinde gelişen, kas atrofisinin de eşlik edebildiği güç kaybı ve silik duyusal bulgularla karakterizedir.…”
