Abstract

Neurological complications of myeloma are relatively common, and include those associated with various metabolic disturbances, hyperviscosity, amyloidosis, peripheral neuropathy, and, occasionally, cranial nerve palsies. Spread to the central nervous system most commonly presents as compression of the spinal cord or cauda equina. We report a relative rare case presenting acute paraparesis initially due to thoracic cord compression by extramedullary extradural plasmacytoma. This 70 year-old man complained of epigastralgia, back pain, and gait disturbance. He fulfilled the diagnostic criteria of myeloma, and later experienced sphincter disturbance. Magnetic resonance imaging showed the tumor compressing the spinal cord at the Th4 level, so, decompressive laminectomy was performed. The tumor extended extramedullary from the Th4 lamina and compressed the dural sac from behind. Microscopic examination indicated plasmacytoma.
