Info

Diffuse symmetrical calcifications in the bilateral basal ganglia, thalami, midbrain (including red nuclei), pons, cerebellar hemispheres (including dentate nuclei), and subcortical white matter of the fronto-parieto-temporal lobes.

Case Discussion

Primary Fahr disease should only be considered when secondary causes of a Fahr syndrome are excluded, such as pseudohypoparathyroidism, mitochondrial diseases, infections (e.g. CMV, HIV), and radiation exposure.
