The MRI hyperintensity reflects the existence of lesions in the brain. These could include: Incontinence. A bony column of vertebrae surrounds and protects your spinal cord. Because this entity is rare and is diagnosed from the clinical standpoint, the radiologist should use this term sparingly or not at all, as a large number of other causes must be excluded before considering TM in the differential diagnosis. Occasionally, a spinal nerve root is subjected to compression or irritation due to several factors. No compressed but maybe abutment of cord. The brain is the bodys control centre. The spinal cord is part of the central nervous system (CNS). Signal change in the cord could be from mechanical injury (cord . Multiple Sclerosis.MS is a demyelinating disease of the central nervous system that is mediated by T cells and macrophages and is characterized by focal symptomatic lesions in the brain and spinal cord (1,6).

Myelopathy is a broad term that references the clinical symptoms related to spinal cord dysfunction such as motor and sensory changes and bowel and bladder dysfunction. In equivocal cases, CT myelography can help localize the dural defect and conventional myelography shows real-time movement of CSF, so that other causes of intradural filling defect such as arachnoid cyst can be excluded (62). What does increased T2 signal intensity mean? The spinal cord is a clinically important site that is affected by pathological changes in most patients with multiple sclerosis; however, imaging of the spinal cord with conventional MRI can be difficult.
