Fahr disease: Idiopathic basal ganglia calcification

A 23-year-old man presented with progressive bulbar and oromandibular dystonia, in addition to distal limbs involvement. In neurological exam, the patient had diverse manifestations, most commonly movement disorder, cognitive impairment, ataxia and speech disorder. Other minor neurologic manifestations included pyramidal signs, psychiatric features, and gait disorders. He had no positive family history, and his parents were not relative. Calcifications in the brain computed tomography scan (CT scan) are seen primarily in the basal ganglia and in other areas such as the cerebral cortex (Figure 1).
