Liechtenstein in 1884 reported the association of PA and spinal cord disease but attributed both to tabes dorsalis. Lichtheim in 1887 and Minnich in 1892 recognized the histologic differences in the spinal cord between PA and tabes dorsalis. In 1900, Russell et al coined the term subacute combined degeneration of the spinal cord Subacute combined degeneration of the spinal cord is due to vitamin B 12 deficiency, such as occurs in pernicious anemia.It is characterized by myelopathy with spasticity, weakness, proprioceptive loss, and numbness due to degeneration of the corticospinal tracts and posterior columns Subacute combined degeneration of spinal cord: symmetrical demyelination of the spinal cord tracts occurs in vitamin B 12 deficiency due to insufficient vitamin B 12-dependent fatty acid synthesis and production/maintenance of myelin. It manifests with the following symptoms Subacute combined degeneration of the spinal cord (vitamin B 12 deficiency) Small-vessel ischemic disease (affecting the brain primarily, and caused by diseases with vascular risk factors, such as diabetes, hypertension, hyperlipidemia, old age Four pairs of monkeys were maintained in an atmosphere of nitrous oxide under conditions which had previously been shown to produce subacute combined degeneration (SCD) of the spinal cord. The diet of one of each pair was supplemented with methionine. In every case the monkey with the unsupplemented diet became ataxic at around 10 weeks and the disorder progressed over a period of 2-3 weeks.

Subacute combined degeneration (SCD) of the spinal cord is a treatable and potentially reversible myelopathy that primarily affects the dorsal and lateral columns. Its causes directly and indirectly involve vitamin B12 deficiency, and symptoms range from mild paresthesias to paraplegia and incontinence Teaching Neuro. Image. : Inverted V sign in subacute combined degeneration of spinal cord. A 60-year-old man presented with 3 months of finger paresthesias. Neurologic examination showed pseudoathetosis in arms, loss of joint position and vibration sensation in toes and fingers, brisk deep tendon reflexes in arms and knees with depressed ankle. The diagnosis of laughing gas-induced combined spinal cord degeneration was evident by the low count of vitamin B 12 combined with lesions shown on magnetic resonance imaging (MRI). Abstaining from the laughing gas, weekly intramuscular injections of hydroxocobalamin and revalidation, she was fully recovered in 8 weeks

The patient usually presents with symptoms of subacute combined degeneration of spinal cord, which manifest with peripheral sensorimotor neuropathy and spastic paraparesis with autonomic dysfunction. On physical examination, the physician often elicits signs of decrease upper and lower motor neuron function This distinctive pattern of abnormal signal intensity was considered characteristic of subacute combined degeneration of the spinal cord. A serum vitamin B 12 test was performed and showed a diminished serum B 12 level of 43 pg/mL (32 pmol/L); this abnormal result was confirmed with a repeat test, which indicated a B 12 level of 51 pg/mL (38.

We describe a case of functional vitamin B12 deficiency where the repeated measurement of a serum B12 level within the normal range led to delay in the diagnosis of subacute combined degeneration of the spinal cord, and possibly permanent neurological damage as a result. Failure of intracellular transport of B12 by transcobalamin-2 can lead to functional B12 deficiency but with apparently. subacute combined degeneration of spinal cord degeneration of both the posterior and lateral columns of the spinal cord, producing various motor and sensory disturbances; it is due to vitamin B 12 deficiency and is usually associated with pernicious anemia. Called also Lichtheim's or Putnam-Dana syndrome Gradient echo sequences should be used, as spin echo sequences may understate the degree of cord haematoma.13 Intramedullary haemorrhage usually presents as a complication of other conditions that may be acute, subacute, stepwise or chronic.14 The underlying cause, such as spinal vascular malformation (most common) or tumours, may also show on. Degenerative diseases such as amyotrophic lateral sclerosis and spinal muscular atrophy. Symptoms vary but might include pain, numbness, loss of sensation and muscle weakness. These symptoms can occur around the spinal cord, and also in other areas such as your arms and legs. Treatments often include medicines and surgery Spinal cord compression is usually secondary to an extrinsic mass. Manifestations may include back and radicular pain (early) and segmental sensory and/or motor deficits, altered reflexes, extensor plantar responses, and loss of sphincter tone (with bowel and bladder dysfunction).

Membranes called the meninges act somewhat like the casing on a sausage, wrapping up the spinal cord, the nerve roots, and the CSF inside the spinal canal. The outermost layer of the meninges is a tough tissue layer known as the dura mater. Degenerative spinal changes can affect almost every structure of the spine. For example Cervical spondylotic myelopathy (CSM) is a neurologic condition that develops insidiously over time as degenerative changes of the spine result in compression of the cord and nearby structures. It is the most common form of spinal cord injury in adults; yet, its diagnosis is often delayed. The purpose of this article is to review the pathophysiology, natural history, diagnosis, and management.

Name the clinical spinal cord syndromes discussed in class. - complete cord syndrome. - Brown-Sequard (hemicord) syndrome. - Anterior cord syndrome. - Dorsal cord syndrome Spinal cord disorders can be devastating, but many are treatable if recognized early (Table 188-1). Knowledge of relevant spinal cord anatomy is often the key to correct diagnosis ( Fig. 188-1 ). Table Graphic Jump Locatio Magnetic resonance imaging of the spinal cord showed symmetric bilateral high signal within the dorsal columns, suggestive of subacute combined degeneration of the cord; magnetic resonance imaging of the brain revealed minimal white matter lesions. Again, her serum vitamin B 12 level was normal, as were thiamine, pyridoxine, and folate values. Folic acid may produce a haematological response in vitamin B12 deficiency but may aggravate the neuropathy and also precipitate subacute combined degeneration of the spinal cord. Large doses of folic acid alone should therefore not be used to treat megaloblastic anaemia unless the serum vitamin B12 level is known to be normal

Vitamin B 12 deficiency can present with neurologic manifestations including subacute combined degeneration of the spinal cord, peripheral neuropathy, optic neuropathy, ataxia, cognitive disturbances, and mood changes, in addition to megaloblastic anemia. 7-9 The deficiency is typically diagnosed by low serum vitamin B 12 levels in. Cervical Facet Dislocations and Fractures represent a spectrum of traumatic injury with a varying degree of cervical instability and risk of spinal cord injury. Diagnosis can be confirmed with radiographs or CT scan. An MRI should be performed before surgery to identify an associated disk herniation These patients were 3 males, affected by MCI, previous stroke and subacute combined degeneration of spinal cord, respectively. Average age was 68.0 ± 11.27 years (range 55-75 years) (see Tables 1 and 2)

Approach to acute or subacute myelopathy Neurolog

Compression of the spinal cord may be due to causes in vertebral column, meninges and in the spinal cord itself. Important causes of compression of the spinal cord are: (1) In the Vertebral Column: (a) Trauma causing vertebral fracture, vascular damage or whiplash injury due to acute stretch-damage of the spinal cord • Acute inflammation of the spinal cord, usually involving a limited segment • Results in sensory, motor, and autonomic dysfunction • Clinical signs are due to the involvement of the ascending and descending tracts in the transverse plane of the spinal cord • Often damages the myelin • Incidence of 1-5 million/yea Significant spinal instability. Sometimes the cervical spine is not stable enough for exercise, such as if a vertebral bone is fractured, or if spinal degeneration causes compression of the spinal cord or a nerve root. In such cases, the spine must be stabilized to prevent further injury before resuming physical therapy BACKGROUND AND PURPOSE: Vitamin B12 deficiency may cause neural injury that results in cognitive deficits. The main purpose of our study was to evaluate morphometric and microstructural changes in the brain and relate them to cognition in subacute combined degeneration of the spinal cord and patients with biochemically deficient vitamin B12

Diphyllobothrium latum, the fish tapeworm, is the biggest tapeworm in humans. It causes a parasitic infection called diphyllobothriasis which is acquired by eating raw fish infected with the parasite. Diphyllobothriasis is found in Chile, Peru, Uganda and in the Northern Hemisphere (northern Asia, Europe and America) in areas of rivers and lakes Covering the entire spectrum of this fast-changing field, Diagnostic Imaging: Spine, fourth edition, is an invaluable resource for general radiologists, neuroradiologists, and trainees—anyone who requires an easily accessible, highly visual reference on today's spinal imaging.
