A 14-year-old male patient, with focal epilepsy. The structural MR images, including axial T2WI (a), axial FLAIR image (b) coronal T2 IR (c), axial DWI (d), as well as axial 3D T1 (e), all are unremarkable and negative. The MV 1H-MRS picture maps demonstrate, the MRS spectra of the right and left temporal lobes reflect the decrease in NAA/(Cho + Cr) and NAA/Cr ratios in the zone of epileptogenic activity in the left temporal lobe measuring 0.6 and 1.1, respectively (f) in comparison with the contralateral non-epileptic right temporal lobe measuring 1 and 2.2, respectively (g). The FA map (h) revealed focal decrease in the FA value in the left temporal lobe measuring 0.22 (white arrow), while MD map (i) reveals focal increase in the MD value in the left temporal lobe measuring 8.8 × 10–3 m2/sec (white arrow). The ASL-MRI color-coded cerebral perfusion map (i) reveals a focal hypoperfusion of the left temporal lobe with rCBF measuring about 69 ml/100 g/min (white arrow). The clinical examinations and EEG studies confirmed our results
