An elderly woman with calcification of the basal ganglia who presented with shuffling gait : a review with a case report

Computed tomography (CT) scan of her brain revealed heavy calcification in the basal ganglia and dentate nuclei (FIGURES 1-3). There was also mild ventricular dilatation and cerebellar atrophy. Her full blood count was normal and B12 was marginally low at 150 pmol/L (normal range, 180-660 pmol/L). Biochemistry—including electrolytes, urea, creatinine, and calcium—was within normal limits, as were thyroid stimulating hormone and rapid plasma reagin levels. Her score on the mini-mental state examination was 21/30.1 Sitting and standing blood pressure was 130/80 mm Hg and central nervous system examination revealed no pyramidal SK Cheong1 MB, BS, FCFPS, DKY Chan2 MD, FRACP
