Physiological intracranial calcification occurs in about 0,3-1,5% of cases. It is asymptomatic and is detected incidentally by neuroimaging. Pathological basal ganglia calcification is due to various causes, such as: metabolic disorders, infectious and genetic diseases and other. Hypoparathyroidism and pseudohypoparathyroidism are the most common causes of pathological basal ganglia calcification. Besides tetany and seizures this condition is presented by parkinsonism and dementia. Such parkinsonism doesn't respond to drugs containing levodopha. Infections (toxoplasmosis, rubella, cytomegalovirus, cysticercosis, AIDS) give multiple and asymmetric intracranial calcification. Inherited and neurodegenerative diseases cause symmetrical, bilateral basal ganglia calcification which is not related to metabolic disorders (blood calcium level and other), those are: Cockayne syndrome, tuberous sclerosis, Fahr's syndrome, Down syndrome and other. We observed some cases of basal ganglia calcification and studied clinical manifestations and treatment tolerance of this pathological condition. Since adequate treatment of hypoparathyroidism may lead to marked clinical improvement, serum concentration of calcium, phosphorus, and parathyreoid hormone is suggested to be determined in all individuals with calcification of the basal ganglia to rule out hypoparathyroidism. Basal ganglia calcification in young patient with acute hepatitis may be result of Wilson disease.

BACKGROUND Basal ganglia calcification (BGC) is a rare sporadic or hereditary central nervous system (CNS) abnormality, characterized by symmetric or asymmetric calcification of the basal ganglia. CASE REPORT We report the case of a 65-year-old Gypsy female who was admitted for a tetanic seizure, and who had a history of polyneuropathy, restless-leg syndrome, retinopathy, diabetes, hyperlipidemia, osteoporosis with consecutive hyperkyphosis, cervicalgia, lumbalgia, struma nodosa requiring thyroidectomy and consecutive hypothyroidism, adipositas, resection of a vocal chord polyp, arterial hypertension, coronary heart disease, atheromatosis of the aorta, peripheral artery disease, chronic obstructive pulmonary disease, steatosis hepatis, mild renal insufficiency, long-term hypocalcemia, hyperphosphatemia, impingement syndrome, spondylarthrosis of the lumbar spine, and hysterectomy. History and clinical presentation suggested a mitochondrial defect which also manifested as hypoparathyroidism or Fanconi syndrome resulting in BGC. After substitution of calcium, no further tetanic seizures occurred. CONCLUSIONS Patients with BGC should be investigated for a mitochondrial disorder. A mitochondrial disorder may also manifest as tetanic seizure.

The authors retrospectively reviewed charts of the children with basal ganglia stroke who either had preceding minor head injury or showed basal ganglia calcification on computed tomography (CT) scan. Twenty children, 14 boys and 6 girls were identified. Eighteen were aged between 7 months to 17 months. Presentation was with hemiparesis in 17 and seizures in 3. Preceding minor head trauma was noted in 18. Family history was positive in 1 case. Bilateral basal ganglia calcification on CT scan was noted in 18. Brain magnetic resonance imaging done in 18 infants showed acute or chronic infarcts in basal ganglia. Results of other laboratory and radiological investigations were normal. Four infants were lost to follow-up, 9 achieved complete or nearly completely recovery, and 7 had persistent neurological deficits. Basal ganglia calcification likely represents mineralized lenticulostriate arteries, a marker of lenticulostriate vasculopathy. Abnormal lenticulostriate vessels are vulnerable to injury and thrombosis after minor head trauma resulting in stroke.
