Pathophysiological mechanisms of sulcal hyperintensity on magnetic resonance imaging with fluid-attenuated inversion recovery sequence and the relationship with seizure in patients with chronic subdural hematoma revealed by 1.5-Tesla arterial spin la
Purpose: The mechanism underlying sulcal hyperintensity observed on fluid-attenuated inversion recovery magnetic resonance imaging (MRI) (sulcal FLAIR hyperintensity [S-FLAIR-HI]) without apparent abnormalities in the cerebrospinal fluid (CSF) is believed to involve alterations in regional hemodynamics, including venous congestion caused by mass effect, leading to a pathological increase in the blood pool-to-CSF ratio. While S-FLAIR-HI is observed in chronic subdural hematoma (CSDH), its exact incidence, mechanism of occurrence, and relationship with seizures remain unclear.
