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 .

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 .

This abnormality routinely resolves following complete dAVF treatment. 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.
