Differential diagnosis of T2 hyperintense spinal cord lesions
White matter hyper-fi intensities are common in MRIs of asymp-tomatic individuals, and their prevalence increases with age from approximately 10% to 20% in those approximately 60 years old to close to 100% in those older than 90 years.T2-weighted signal hyperintensity within the viable (enhancing) portion of the lesion is highly suggestive of benign histology . In older patients, diffuse T2-weighted hyperintensity of the cerebral white matter can be found as an expression of vascular .0000000000000909.

It has been speculated that the FLAIR hyperintensity may be due not only to T2-weighted prolongation reflecting the elevated protein content but also to the T1-weighted shortening effects of melanin [ 19, 20 ].Another finding in ALS is hyperintensity along the corticospinal tracts (CST) on T2-weighted and/or fluid-attenuated inversion recovery (FLAIR) sequences.3 They are more common in individuals with a history of cognitive impairment, dementia, or cerebrovascular .

It is a common . Hyperintense spinal cord signal on T2-weighted images is seen in a wide-ranging variety of spinal cord processes. However, T2-weighted signal intensity is not a reliable predictor of benignity in irregular or spiculated masses.

Imaging approach to the cord T2 hyperintensity (myelopathy) Radiol Clin North Am.For example, lipid-containing lesions frequently produce chemical shift artifact, and some melanin-containing lesions exhibit a combination of high signal intensity on T1-weighted images and low signal intensity on T2-weighted images. These results indicate T2/FLAIR hyperintensity is a marker of cortical venous hypertension. Subchondral linear hyperintensity was seen in 15/16 (93.
