Abnormal calcium deposits in areas of the brain that control movement, including the basal ganglia and the cerebral cortex are, the hallmark of Fahr's syndrome, a rare genetically dominant, inherited neurological disorder. We are going to introduce a 29-year-old woman who was admitted to our hospital because of progressive abnormal posture in her arms and behavioral changes. Throughout the neurological examination, the patient had slurred speech, mild bradykinesia, a masked face, dystonic posture in her left hand, and accentuated dystonic posture in her left foot while standing and walking. Significant bilateral calcifications were detected in the basal ganglia, dentate nuclei, and cerebral cortices on the brain CT scan. Idiopathic bilateral striopallidodentate Calcinosis, also known as Fahr's syndrome, was clinically diagnosed after all other possible causes of the bilateral calcification were ruled out. These reports, along with findings of imaging and symptom presentation, can be helpful to increase understanding of this disease because our current knowledge of fahr syndrome is limited and the set of symptoms in these patients is diverse including psychiatric symptoms, behavioral and cognitive changes, and abnormal movements.
