Question

on examination of a patient the following findings are obtained. the patient has paraplegia of the right lower limb. the patient also shows loss of pain and temperature sensation of the left lower extremity with loss of position and vibration sense on the right. what is this a description of? myasthenia gravis arnold - chiari syndrome syringomyelia syndrome compartmental syndrome brown - sequard syndrome

Explanation:

Brown - Sequard syndrome is characterized by ipsilateral (same - side) paralysis (such as right lower limb paraplegia here), ipsilateral loss of position and vibration sense, and contralateral (opposite - side) loss of pain and temperature sensation (left lower extremity in this case). Myasthenia gravis is a neuromuscular disorder with muscle weakness mainly in voluntary muscles, not these specific sensory and motor deficits. Arnold - Chiari syndrome is related to malformation of the hindbrain. Syringomyelia is a disorder with fluid - filled cavities in the spinal cord and has different clinical manifestations. Compartmental syndrome is related to increased pressure within a muscle compartment, not these neurological sensory - motor patterns.

Answer:

E. Brown - Sequard syndrome
