WebbThey appear hypointense on T1-weighted sequences and hyperintense on T2*-weighted sequences, the most sensitive is the FLAIR sequence. White matter hyperintensities reflect various pathological changes such as ischemic lesions, myelin sheath loss, small vessel disease, gliosis, micro-bleedings or breaches to CSF-brain barrier ( Raz, Yang, Dahle, & … WebbCONCLUSION: 1. Region of abnormal T2/FLAIR hyperintensity at the gray-white junction of a elongated segment of mesial right frontoparietal cortex is nonspecific but active cerebritis/vasculitis may be considered. Follow-up to exclude underlying neoplasm is recommended. A few foci of serpentine or tubular shaped enhancement are seen within …
