Abstract

Advances in surgical techniques, neuroimaging, and white matter fiber dissection have facilitated the identification of critical tracts like the frontal aslant tract (FAT) that have garnered attention, despite remaining poorly recognized within the neurosurgical community. We report the case of a 37-year-old male right-handed patient presenting with headache and epilepsy, in whom neuroimaging revealed an intra-axial lesion in the left middle frontal gyrus closely associated with FAT. Successful navigation-guided resection of the lesion was achieved, resulting in a favorable neurological outcome attributable to the preservation of the tract. This case is complemented by a review of the literature and anatomical dissection of FAT in a human specimen. The FAT has emerged as a critical white matter structure in neurosurgery, given its involvement in speech and motor functions. This case demonstrates the importance of advanced imaging modalities and intraoperative technologies to ensure safe resection.
