Fahr syndrome, also known as bilateral striatopallidodentate calcinosis, is characterised by abnormal vascular calcium deposition, particularly in the basal ganglia, cerebellar dentate nuclei, and white matter, with subsequent atrophy. It can be either primary (usually autosomal dominant) or secondary to a large number of underlying illnesses or metabolic disturbances. #fahr #syndrome #striatopallidodentate #calcinosis #calcium #brain #ct #radiology
