Patient with a case of suspected occipital lobe epilepsy.
Structural MR is normal: No structural lesion detected with FLAIR sequence or
asymmetric perfusion 3D ASL. Right occipital ictal hyperperfusion localized on
subtraction ictal SPECT co-registered MR (SISCOM). Patient underwent PET/MR,
which demonstrated right temporo-occipital hypometabolism in interictal PET/MR,
that is much more widely distributed than as depicted on the SISCOM image.
