Amyothropic neuralgy is a rare disease witch unknown etiopathogenesis. The main popular theory says that inflammatory and immunomodulatory process is connected with that disease. Diagnosis is made after exclusion of other causes of plexus lumbosacralis damage. The main symptom is neuropathic pain after which there is observed muscle weakness and atrophy. ENG/EMG study and MRI are made to confirm the diagnosis. In this study we described a case of 52 years old female with lower limbs paresis, who was diagnosed few years after first symptoms. Limb paresis was preluded by lumbar pain. MRI study revealed central spinal disc herniations on L1-2, L2-3, L3-4 levels with dura matter compression, L4-5 spinal disc right lateral herniation and synovial cyst. MRI of both lumbar plexuses was also normal. EMG study revealed features of bilateral, chronic damage of lower legs nerves on lumbar plexus level. Patient was treated with physiotherapy and gabapentin with dose of 2x600mg per day.
