Fahr's syndrome is a rare clinical entity consisting of certain metabolic, biochemical, neuroradiologic and neuropsychologic phenomena in which extrapyramidal phenomenology clinically dominates. In this report, primarily from educational reasons, we have presented a female patient, who was before admittance to our clinic examined in one Belgrade hospital for headache, stiffness of trunk and extremities and the diagnosis was migraine with depressive reactions. However, as the discomforts were persistent, she was admitted to our clinic and after the investigation, especially for the presence of extrapyramidal clinical phenomenology with dominantly pronounced increase of tonus with the presence of amorphous calcifications in basal ganglia on both sides it was concluded that she was suffering from Fahr's syndrome.
