Cerebral cortical T1 hyperintensity or gyriform T1 hyperintensity refers to curvilinear hyperintense signal involving the cerebral cortex on T1-weighted images on brain MRI.
Causes include:
- accumulation of denatured proteins and/or lipid-laden macrophages
- accumulation of methemoglobin in cortical hemorrhagic infarcts
