case_images: B12 and folate dosage, serology for syphilis and thyroid hormones were normal. Brain computed tomography (CT) and Magnetic Resonance Imaging (MRI) showed frontal atrophy which was disproportional for age. (Figure 1), while brain SPECT showed moderate cortical hypoperfusion, mainly to frontal lobes (Figure 2).
