ABSTRACT

Diffuse Idiopathic Skeletal Hyperostosis (DISH); is an idiopathic chronic disease characterized by ossification in the ligament and tendon adhesion regions, which are more common in men and after fifth decade. Neurological tables attached to DISH are very rare and include spinal canal stenosis and myelopathy. The development of thoracic myelopathy and neurological deficit attached to ligamentum flavum ossification (LFO) is rarely seen. Cauda equina syndrome may be accompanied by bilateral or unilateral leg pain with severe back pain, saddle-like perianal hypoesthesia or anesthesia, loss of strength as far as progressive paraplegia on the lower extremity, loss of sensation and urinary incontinence. In this case report, acute paraplegia thought to be due to calcified ligamentum flavum at T9-10 level caused by spinal cord pressure in a patient with DISH without trauma and spontaneous L1-2 seqestration as cause of pressure of cauda equina fibers was aimed to be presented in the light of literature information.
