White matter hyperintensities (WMHs) are brain lesions that appear as regions of enhanced brightness on T2-weighted magnetic resonance imaging (MRI). Typically, the T1 signal intensity is lower than that of liver and the T2 signal is heterogenously hyperintense. Hyperintensity is a term used in MRI reports to describe how part of an image looks on MRI scan. rim enhancement of capsule may persist. they are defined as hyperintensities on the FLAIR of at least 3 mm in size, that can be distinguished from dilated perivascular spaces (which appear isointense on FLAIR).

The differential diagnosis includes a large number of diseases that affect the spinal cord. Lymphangioma appears as a well-circumscribed unicystic or multicystic, homogeneous, or heterogeneous mass.4,32 The lesion may show an isointense or hyperintense signal on Tl-weighted images and an isointense or hypointense signal on T2-weighted images with respect to the vitreous (Table 10.4).
