This report describes an exciting presentation of neuroblastoma manifesting as conus medullary syndrome. Below this region is a group of nerve roots called the cauda equina. Background Spontaneous conus medullaris infarction is a rare disease. Conus medullaris comprises of a spinal cord and is in proximity to the nerve roots. In patients with cauda equina syndrome, something compresses on the spinal nerve roots. Netter's Orthopaedics 1st ed. Empiric treatment for Guillain Barre Syndrome (GBS) was ineffective and a repeat MRI with gadolinium found an expanding conus medullaris lesion with linear spinal cord enhancement. If extrusion of D12-L1 disc is also involved, this may lead to other problems like acute paraplegia. Acute vs. chronic injuries; complete vs. incomplete injuries "Acute"=sudden onset of symptoms "Complete" ? Hence, conus medullaris syndrome is a combination of upper motor neuron (UMN) and lower motor neuron (LMN) lesion. Signs are almost identical to those of the cauda equina syndrome, except that in conus medullaris syndrome signs are more likely to be bilateral; sacral segments occasionally show preserved Conus medullaris is the end part of spinal cord.

Pre-eclampsia might . What are the differences between UMN and LMN? herniated disc. Hence, cauda equina syndrome is a lower motor neuron (LMN) lesion. Extending from the conus is a delicate strand of fibrous tissue . Conus medullaris syndrome is caused by an injury or insult to the conus medullaris and lumbar nerve roots. Despite some delay in diagnosis, we were able to induce a complete remission by intense chemotherapy, the second case ever reported of the successful chemotherapy for paraplegic IVL. The conus medullaris is the terminal end of the spinal cord.. Practitioners should not assume that implantation of intrathecal catheters with their tips located at or below the conus medullaris will eliminate . Terminology Plegia = complete lesion Paresis = some muscle strength is preserved Tetraplegia (or quadriplegia) Injury of the cervical spinal cord Patient can usually still move his arms using the segments above the injury (e.g., in a C7 injury, the patient can still flex his forearms, using the C5 segment) Paraplegia Injury of the . This can often improve after a Durotomy is performed. Conus Medullaris Syndrome Injury to sacral cord, lumbar nerve roots causing -Areflexic bladder -Loss of control of bowels -Knee jerk relexes preserved, ankle jerk absent -Signs similar to cauda equina syndrome except more likely to be bilateral 5 Lumbar level Lumbar level - Round cord, ventral horn enlargements. Conus medullaris syndrome. The most caudal part of the spinal cord shows special anatomical characteristics and it contains epiconus (L4-S2 segments), the conus medullaris (S3-S5 segments), and surrounding nerve roots. Referred to physical therapy What's the diagnosis? The conus medullaris is the terminal end of the spinal cord.
Compression of spinal cord at this level is conus medullaris syndrome. In the other fetus, the tethered cord was part of a caudal regression syndrome with partial agenesis of the .
The conus medullaris is tethered to the coccyx by a fibrous cord called the filum terminale, which stabilizes the distal end of the spinal cord. Introduction.

Lumbar spine MRI demonstrated conus enlargement and an intramedullary mass of predominant isointensity, heterogeneity with central necrosis, and marked heterogeneous enhancement ( figure 1 ). It is a clinical subset of spinal cord injury syndromes. The anatomical variation in conus medullaris termination and the theoretical possibility of occult tethered cord syndrome make it difficult to consider an abnormal caudal position of the conus medullaris as a reliable diagnostic criterion in dogs . A 22-year-old man presented with a 3-month history of back pain and numbness of the left lower extremities. The conus medullaris can be identified as a dark triangular structure with two surrounding echogenic lines at the caudal end of the spinal cord. e) Cauda equina syndrome involves injury to the lumbosacral nerve roots and is characterized by an areflexic bowel and/or bladder . 20062.
