Hypoparathyroidism – most common systemic cause • ↓ PTH → ↓ calcium, ↑ phosphate • Leads to symmetrical basal ganglia calcifications • May be idiopathic or post-surgical 2. Pseudohypoparathyroidism • PTH resistance; biochemical profile resembles hypoparathyroidism 3. Hyperparathyroidism • Less common, but can also lead to intracranial calcifications 4. Other metabolic disorders • Hypomagnesemia, hypop...")
