A computed tomography (CT) is useful in diagnosing and determining the extent of BSPDC. Here we report a 48-year-old woman presenting to the emergency department with a sudden onset conscious loss followed by general convulsions. She had undergone a total thyroidectomy for a benign thyroid goitre 20 years ago. A marked decrease in the serum calcium level (4.7 mg/dL) was noted. The diagnoses of hypoparathyroidism and primary hypothyroidism were also confirmed thereafter. A non-contrast head CT (figure 1) revealed symmetric intracranial calcifications, including subcortical white matter, thalami, basal ganglia, caudate nuclei and cerebellums. After the correction of hypocalcaemia with intravenous
