Ganglion cysts usually originate from vertebral facet joints in the spine and they are often located dorsal portion of the facet so usually asymptomatic. In this case, we report a 60 year-old woman presented with suddenly developed lower back pain and right leg foot-drop. Lumbar Magnetic Resonance Imaging re¬vealed a large cystic lesion at L5 body level. The cystic lesion removed with standart microsurgical method. The histopathological findings were consistent with ganglion cyst. To our knowledge, this is the first report, the cause of foot-drop in a patient with ganglion cyst without any bleeding in the spine.
