A rare pathologic condition causing lumbar myelopathy in an elderly patient is described, and the onset mechanism is discussed based on operative findings. A 69-year-old female presented a slow onset of pain extending from the low back to the right lower extremity, followed by a vesico-rectal disturbance. The diagnosis of low lumbar myelopathy was established by magnetic resonance imaging (MRI) and computed tomography (CT) myelography. At operation the low placed conus medullaris was discolored and the epiconus was severely compressed by the narrowed spinal canal. However, the filum terminale was neither "taut" nor "thickened". Decompression of the narrowed portion improved the symptoms. We consider that the narrowed spinal canal due to spondylotic change played the most important part in the development of the symptom of this elderly patient with the low placed conus medullaris.
