A 46-year-old woman with slight low back pain for nearly 15 years complained of severe radiating pain in her left leg since 3 months. The 4th lumbar disc hernia was suspected by physical and roentgenographic examination. At Love's operation, a extradural tumor was found beneath the nerve root. The tumor mass was dark red in color and tip of the little finger in size.
Histological examination revealed that the tumor was chordoma composed of vacuolated cells with a little intracellular mucin.
