what's the cause of conus medullary syndrome? in HY neuroanat, it says intramedullary tumor but what does that mean? how is this different from the cause of cauda equina syndrome? thanks.

the causes of both syndromes can be myriad like
Lumbar stenosis (multilevel)
Spinal trauma including fractures
Herniated nucleus pulposus (cause of 2-6% of cases of cauda equina syndrome)
Neoplasm, including metastases, astrocytoma, neurofibroma, and meningioma: Twenty percent of all spinal tumors affect this area.
Spinal infection/abscess, such as tuberculosis, herpes simplex virus, meningitis, meningovascular syphilis, cytomegalovirus, or schistosomiasis
Idiopathic, eg, spinal anesthesia: These syndromes may occur as complications of the procedure or of the anesthetic agent (eg, hyperbaric lidocaine, tetracaine).
Spina bifida and tethered cord syndrome
the difference usuallly lies in following:
onset conus medulary synd is quick n bilateral
cauda equina syndrome (CE) is unilateral and gradual
CM has knee reflex preserved ankle lost
CE has both lost
CM sensations are usually lost around the anal region...consider that the last Sacral and coccygeal segments are lost..
in CE ...saddle anesthesia is present
CM has more back pain
CE has les back pain
CM has frequent impotence and sphincter dysfunction that appears early in the disease...
CE has late onset of these...
causes are similar in both cases as told above
