Figure 2: Matched transverse slices showing multimodal brainimaging: T1-weighted MRI (A), FDG PET during (B) and after (C)the hypoglycemic coma episode. During the coma episode (B) FDGPET showed hypometabolism of bilateral precuneus, left pre- andpostcentral regions, left insula, left temporal regions and bilateraloccipital regions (the patient’s eyes were closed). After the comaepisode (C), FDG PET showed a marked improvement ofpreviously observed metabolic abnormalities as only the lefttemporal pole remained hypometabolic.
