Coarse bilateral calcifications in region of globus pallidus.
No calcifications in cerebellum or cortex.
No acute intracranial abnormalities.
Case Discussion
Although basal ganglia (and specifically globus pallidus) calcification is a relatively common finding, given this patient's psychiatric background and subtle neurological findings (choreic gait) it was felt that Fahr syndrome was a likely diagnosis.
