2024年8月27日 · Cauda equina syndrome (CES) is considered an incomplete cord syndrome, even though it occurs below the conus. Cauda equina syndrome refers to a collection of symptoms and signs that result from severe compression of the …

2024年1月20日 · MRI. Similarly, on MRI these masses usually appear as well-circumscribed masses, inferior to the conus. With some lesions, the characteristic salt-and-pepper appearance of neck and skull base paragangliomas may also be seen. Associated syringohydromyelia has been reported in some cases. Reported signal characteristics include: T1: isointense. T2

2024年5月29日 · The cauda equina is the collective term given to nerve roots distal to the conus medullaris, which occupy the lumbar cistern. Its name comes from the Latin for "horse's tail". The cauda equina is contained within the thecal sac and suspended in cerebrospinal fluid (CSF) .

2024年10月6日 · MRI. It is essential that contrast is administered if the diagnosis is suspected as non-contrast sequences are essentially normal 2. Typical findings in Guillain-Barré syndrome are thickening and contrast enhancement of the spinal nerve roots, especially in the region of the cauda and conus medullaris 2.

2024年4月23日 · After the cord terminates, the nerve roots descend within the spinal canal as individual rootlets, collectively termed the cauda equina. Variant anatomy. The termination of the conus medullaris has been reported from mid-T11 to mid-L3 vertebral body levels.

2024年12月4日 · Nerve root and cauda equina enhancement Nerve root enhancement is a phenomenon described on post-contrast MRI scans that can be observed in several situations. Pathology

2023年9月26日 · MRI. The abnormality typically is linear and extends over some distance. Signal follows that of fat on all sequences and can demonstrate chemical shift artifact on T2* / gradient weighted sequences. T1: hyperintense T2: hyperintense. fat saturated sequences: signal loss demonstrated T1 C+ (Gd): no enhancement

Abnormal pial enhancement of the conus, with numerous multilevel nodular enhancing foci along the nerve roots of the cauda equina. There is also diffuse dural enhancement, particularly posteriorly. Extensive enhancing metastases seen throughout the …

2024年8月27日 · Unlike cauda equina syndrome which will only have lower motor neuron deficits, conus medullaris will have a combination of upper and lower motor neuron involvement 3. Pathology. The conus medullaris lies in close proximity to nerve roots and injury to this region results in combined upper motor neuron and lower motor neuron features. Etiology
