Syringomyelia was described by Etienne, Morgagni and Santorini in 1594 for the first time and was named by Olliver in 1824. In spite of hundreds of years study, it's cause is still not distinctly known and symptoms are very much variable because of its wide, irregular lesion in the spinal cord. The patient of 34 years old male had been suffered from sensory and temperature dissociation and muscle weakness of lower extremity including lower trunk for two years. In case of classical syringomyelia, sense of pain and temperature were diminished on the same area but this patient had complained disturbance of pain and light touch on the same area, but temperature loss does not coincides with, as figure shows. This report will review syringomyelia of lumbosacral type with a case history and references which is relatively rare in incidences.
