Although the sulcal hyperintensity on fluid-attenuated inversion recovery (FLAIR) images is detected in some chronic subdural hematoma (CSDH) cases, its clinical significance remains determined. A 77-year-old man with symptomatic CSDH presented with generalized tonic-clonic seizures at 9 days after surgery. I-iomazenil -single photon emission computed tomography revealed transient reduction in cortical benzodiazepine receptors binding potential at the region corresponding to that of the sulcal hyperintensity on FLAIR images. Findings of sulcal hyperintensity on FLAIR imaging under the CSDH may have a relation with the cause of epileptic seizure.
尽管在一些慢性硬膜下血肿（CSDH）病例中可检测到液体衰减反转恢复（FLAIR）图像上的脑沟高信号，但其临床意义仍未明确。一名77岁有症状的CSDH男性患者在术后9天出现全身强直阵挛性发作。碘西泮 - 单光子发射计算机断层扫描显示，在与FLAIR图像上脑沟高信号区域相对应的部位，皮质苯二氮䓬受体结合潜能出现短暂降低。CSDH情况下FLAIR成像上脑沟高信号的表现可能与癫痫发作的原因有关。
