FCD type IIIa–HS in a 29-year-old patient with a history of seizures, onset at 15 years of age. A, T1-weighted axial image has normal findings. B and C, PET and PET-T1WI fused images (arrows) indicate a well-defined area of focal hypometabolism in the left temporal lobe region. However, ASL and ASL-T1WI fused images (D and E, arrows) have normal findings in the same brain region. After a left anterior temporal lobectomy, histopathologic findings of the surgical specimen were consistent with FCD type IIIa–HS. This patient with TLE had an Engel class I outcome after >1 year of follow-up.
