Basal ganglia calcification on CT

The faint white stippling in the basal ganglia region is calcification.
Calcification is better seen on a CT scan than MRI. MRI will show low intensity on T2 which is often missed. Causes include
1. Metabolic: hypocalcemia due to hypoparathyroidism, pseudohypoparathyroidism and hyperparathyroidism
2. Birth asphyxia
3. Infections: TORCH, CNS TB, CNS HIV, neurocysticercosis, toxoplasmosis
4. Genetic disorders- mitochondrial, Hallervorden Spatz disease
5. Toxins- CO and lead poisoning.
6. Idiopathic- Fahr disease

These small reddish brown papules are tiny angiofibromas. They appear on the nose and cheeks in a butterfly distribution. The problem is mainly cosmetic. May be removed using dermabrasion, laser ablation or radiofrequency abrasion.
