Myeolography, including post-myelographic CT is likely the most effective imaging study an accurate diagnosis.

Surgical management options include extensive cervical laminectomy with or without an additional posterior arthrodesis, anterior decompression and arthrodesis, and posterior cervical laminoplasty. Treatment decisions can be made based on a grading systems devised by Hirabayashi et al., supplemented by the Nurick myelopathy classification system.

Cerebral angiography and magnetic resonance imaging, family medical history, symptoms, a complete physical examination, and ultimately biopsy of the brain, are often required for the diagnosis. Also, many lab tests must be done for the diagnosis; tests may reveal anemia (a shortage of red blood cells), a high white blood cell count, a high platelet count, allergic reactions, immune complexes, antibodies (tools the body uses to fight off threats) and elevation of inflammatory markers. Another crucial part in the diagnosis of cerebral vasculitis is the use of imaging techniques. Techniques such as conventional digital subtraction angiography (DSA) and magnetic resonance imaging (MRI) are used to find and monitor cerebral involvement.

The treatment for Morquio syndrome consists of prenatal identification and of enzyme replacement therapy. On 12 February 2014, the US Food and Drug Administration approved the drug elosulfase alfa (Vimizim) for treating the disease.

Treatment is first with many different high-dose steroids, namely glucocorticoids. Then, if symptoms do not improve additional immunosuppression such as cyclophosphamide are added to decrease the immune system's attack on the body's own tissues. Cerebral vasculitis is a very rare condition that is difficult to diagnose, and as a result there are significant variations in the way it is diagnosed and treated.

Cobb syndrome is a rare congenital disorder characterized by visible skin lesions with underlying spinal angiomas or arteriovenous malformations (AVMs). The skin lesions of Cobb syndrome typically are present as port wine stains or angiomas, but reports exist of angiokeratomas, angiolipomas, and lymphangioma circumscriptum. The intraspinal lesions may be angiomas or AVMs and occur at levels of the spinal cord corresponding to the affected skin dermatomes. They may in turn produce spinal cord dysfunction and weakness or paralysis.

The disorder was first described by Berenbruch in 1890, but became widely known only after Cobb's report in 1915. Cobb syndrome is thought to be more common in males and have no racial predilection, but only a few dozen cases are known. It is believed to be due to a sporadic mutation, since parents of affected children usually have no evidence of the disease.

While recent case series (n=9-80) studies have found a mortality rate of 20-40%, a large (n=1641) 2009 study reported a mortality rate of 7.5%.

Myelopathy is primarily diagnosed by clinical exam findings. Because the term "myelopathy" describes a clinical syndrome that can be caused by many pathologies the differential diagnosis of myelopathy is extensive. In some cases the onset of myelopathy is rapid, in others, such as CSM, the course may be insidious with symptoms developing slowly over a period of months. As a consequence, the diagnosis of CSM is often delayed. As the disease is thought to be progressive, this may impact negatively on outcome.

Once the clinical diagnosis "myelopathy" has been established, the underlying cause needs to be investigated. Most commonly this involves the use of medical imaging techniques. The best way of visualising the spinal cord is Magnetic Resonance Imaging (MRI). Apart from T1 and T2 MRI images, which are commonly used for routine diagnosis, more recently the use quantitative MRI signals is being investigated. Further imaging modalities used for evaluating myelopathy include plain X-rays for detecting arthritic changes of the bones, and Computer Tomography, which is often used for pre-operative planning of surgical interventions for cervical spondylotic myelopathy. Angiography is used to examine blood vessels in suspected cases of vascular myelopathy.

The presence and severity of myelopathy can also be evaluated by means of Transcranial Magnetic Stimulation (TMS), a neurophysiological method that allows the measurement of the time required for a neural impulse to cross the pyramidal tracts, starting from the cerebral cortex and ending at the anterior horn cells of the cervical, thoracic or lumbar spinal cord. This measurement is called "Central Conduction Time" ("CCT"). TMS can aid physicians to:

- determine whether myelopathy exists

- identify the level of the spinal cord where myelopathy is located. This is especially useful in cases where more than two lesions may be responsible for the clinical symptoms and signs, such as in patients with two or more cervical disc hernias

- follow-up the progression of myelopathy in time, for example before and after cervical spine surgery

TMS can also help in the differential diagnosis of different causes of pyramidal tract damage.

The disease is present at birth, but clinical manifestations are often not seen until later in life. Patients typically experience the sudden onset of pain, numbness, or weakness in their extremities as children or young adults. These symptoms may remit or remain stable and often can be localized below a specific dermatome. Symptoms tend to worsen over time either by discrete steps or continuously. Early development of weakness may portend a more aggressive course. Less commonly, weakness or bowel and bladder dysfunction may be presenting symptoms.

The major debility from Cobb syndrome is the onset of weakness, paresis, sensory loss, and loss of bowel and bladder control. A possible complication if treatment is delayed is Foix-Alajouanine disease or subacute necrotic myelopathy due to thrombosis in the spinal angioma.

Cutaneous lesions may be distributed anywhere in the dermatome, from midline back to abdomen. Midline back lesions may be associated with spina bifida. The cutaneous lesion may be very faint and may be more pronounced when the patient performs a Valsalva maneuver which increases abdominal pressure and causes preferential filling of the cutaneous angioma. Neurological examination will reveal weakness or paralysis and numbness or decreased sensation with a sharp upper cutoff.

The detection of spinal stenosis in the cervical, thoracic or lumbar spine confirms only the anatomic presence of a stenotic condition. This may or may not correlate with the diagnosis of spinal stenosis which is based on clinical findings of radiculopathy, neurogenic claudication, weakness, bowel and bladder dysfunction, spasticity, motor weakness, hyperreflexia and muscular atrophy. These findings, taken from the history and physical examination of the patient (along with the anatomic demonstration of stenosis with an MRI or CT scan), establish the diagnosis.

Cerebrospinal fluid (CSF) analysis shows a large number of white blood cells. Typically small mature lymphocytes are the majority of cells seen, with monocytes and neutrophils making up the rest. Definitive diagnosis is based on histopathology, either a brain biopsy or post-mortem evaluation (necropsy). A CT scan or MRI will show patchy, diffuse, or multifocal lesions. For a number of years, the basic treatment was some type of corticosteroid in combination with one or more immunosuppressive drugs, typically cytosine arabinoside and/or cyclosporine or other medications such as azathioprine, cyclophosphamide, or procarbazine, of which were usually added one at a time to the corticosteroid until a successful combination was found. There is evidence that treatment with radiation therapy for focal GME provides the longest periods of remission.

Differentiation between this and SCC would be based on a history of recent trauma or dental treatment in the area.

Immunohistochemistry may aid the diagnosis. If the lesion is NS, there will be focal to absent immunoreactivity for p53, low immunoreactivity for MIB1 (Ki-67), and the presence of 4A4/p63- and calponin-positive myoepithelial cells.

Fournier gangrene is usually diagnosed clinically, but laboratory tests and imaging studies are used to confirm diagnosis, determine severity and predict outcomes. X-rays and ultrasounds may show the presence of gas below the surface of the skin. A CT scan can be useful in determining the site of origin and extent of spread.

MRI is the preferred method of diagnosing and evaluating spinal stenosis of all areas of the spine, including cervical, thoracic and lumbar. MRI is useful to diagnose cervical spondylotic myelopathy (degenerative arthritis of the cervical spine with associated damage to the spinal cord). The finding of degeneration of the cervical spinal cord on MRI can be ominous; the condition is called myelomalacia or cord degeneration. It is seen as an increased signal on the MRI. In myelopathy (pathology of the spinal cord) from degenerative changes, the findings are usually permanent and decompressive laminectomy will not reverse the pathology. Surgery can stop the progression of the condition. In cases where the MRI changes are due to Vitamin B-12 deficiency, a brighter prospect for recovery can be expected.

This syndrome has two forms, A and B, referred to as Morquio A and Morquio B syndrome or MPA IVA and MPS IVB. The two forms are distinguished by the gene product involved; A involves a malfunction in the GALNS gene product (galactosamine-6 sulfatase), while B involves a malfunction of the GLB1 gene product (beta-galactosidase).

Stimmler syndrome is a rare autosomal recessive congenital disorder first described by Stimmler et al. in 1970. It is characterized by dwarfism, diabetes, a small head, and high levels of alanine in the urine.

Symptoms for the disease include microcephaly, a low birth weight, dwarfism, small teeth, and diabetes. The symptoms of Stimmler syndrome are closely related to a disease studied by Haworth et al. in 1967 as well as Leigh subacute necrotizing encephalopathy with lactic acidosis

The treatment and prognosis of myelopathy depends on the underlying cause: myelopathy caused by infection requires medical treatment with pathogen specific antibiotics. Similarly, specific treatments exist for multiple sclerosis, which may also present with myelopathy. As outlined above, the most common form of myelopathy is secondary to degeneration of the cervical spine. Newer findings have challenged the existing controversy with respect to surgery for cervical spondylotic myelopathy by demonstrating that patients benefit from surgery.

Spinal arteriovenous malformations (AVMs, or angiomatous malformations) are congenital (from birth) abnormalities of blood vessels. Arteries that directly communicate with veins bypass the capillary network (which has not yet developed) and thus creates a shunt. AVMs appear as a mass of , dilated vessels. In regards to the spinal cord, they are usually located in the thoracolumbar region (between the thoracic and lumbar regions, 60% of the time), as opposed to the upper thoracic (20%) and cervical regions (approximately 15%). Cervical malformations arise from the anterior spinal artery and lie within the cord, whereas thoracolumbar malformations can be internal, external or encompass both areas of the cord.

Malformations can be recognised as part of an acute illness or gradual onset disease. In diseases such as subarachnoid hemorrhage, signs and symptoms include headache, neck stiffness and back and leg pain. Extradural, subdural and intramedullary hematomas are all signs of acute cord compression. Gradual onset diseases are more common (85-90% of all diseases leading to a diagnosis of malformation) and are usually due to an increased venous pressure. Other factors such as thrombosis or arachnoiditis can be involved. A bruit (unusual blood sounds) may be heard overlying the spinal arteriovenous malformation. Very occasionally, nevus (moles) or angiolipomas are found.

Myelography is used to confirm the diagnosis of AVMs and it shows 'snake-like' vessels on the cord's surface. If the myelogram is positive, angiography is required to show the extent of malformation and the exact site of the shunt. Magnetic resonance imaging (MRI) may show the appropriate area. If AVMs are left untreated, 50% of patients with gradual symptoms will be unable to walk within 3 years of onset. Operations can prevent progression and may improve any gait or incontinence.

Wobblers is definitively diagnosed by x-ray, nuclear scintography or bone scan. X-rays will show channel widening or filling the easiest and are often most cost effective to horse owners. X-rays will also show any structural anomaly, arthritis, facet remodeling, or bone spurs present. Preliminary diagnosis can be made by ultrasound but x-rays are needed to measure the true depth of facet involvement. For extent of damage to associated structures, veterinarians may opt to have the horse undergo a bone scan or nuclear scintography.

For diagnosis of NPSLE, it must be determined whether neuropsychiatric symptoms are indeed caused by SLE, whether they constitute a separate comorbid condition, or whether they are an adverse effect of disease treatment. In addition, onset of neuropsychiatric symptoms may happen prior to the diagnosis of lupus. Due to the lack of uniform diagnostic standards, statistics about NPSLE vary widely.

Tests which aid in diagnosis include MRI, electrophysiological studies, psychiatric evaluation, and autoantibody tests.

A spinal tap is performed in the low back with dye injected into the spinal fluid. X-Rays are performed followed by a CT scan of the spine to help see narrowing of the spinal canal.

This is a very effective study in cases of lateral recess stenosis. It is also necessary for patients in which MRI is contraindicated, such as those with implanted pacemakers.

The prognosis for Tropical spastic paraparesis indicates some improvement in a percentage of cases due to immunosuppressive treatment. A higher percentage will eventually lose the ability to walk within a ten-year interval.

Surfer's myelopathy is a rare nontraumatic paraparesis. It is a spinal cord injury caused by hyperextension of the back. When the back is hyperextended, a blood vessel leading to the spine can become kinked, depriving the spinal cord of oxygen

The condition gets its name because the phenomenon is most often seen in those surfing for the first time, but it can be caused by any activity in which the back is hyperextended (yoga, pilates, etc). In some cases the paralysis is permanent. As of 2007 there were 9 recorded cases. A case series of 19 novice surfers with nontraumatic myelopathy was published in 2012, with all patients' MRI scans showing hyperintensity from the lower thoracic spinal cord to the conus medullaris. An additional study of 23 cases was published in 2013.

FDG positron emission tomography (PET) may be useful to detect the condition early. Other imaging studies including MRI, CT scans, and X-rays may reveal inflammation and/or damaged cartilage facilitating diagnosis.
