Basal ganglia calcification (BGC) is now being diagnosed with increasing frequency with widespread application of computed tomography (CT) in clinical practice and is no more considered a rarity. During the period 1987 to 1995, 42 patients were noted to have BGC and it constituted 0.93% of all CT scan of brain carried out during the relevant period. These patients presented with diverse neurological and endocrine disorders i.e., epilepsy (22 patients), mental retardation (five patients), extra-pyramidal syndromes (five patients), abnormal behaviour (three patients), stroke (two patients), raised intracranial tension without localizing signs (one patient), following radiotherapy (one patient), and with hypoparathyroidism (three patients). These patients were noted to have variable degree of calcification in different parts of brain i.e., basal ganglia (42 cases), cerebellum (12 cases) and cerebral cortex (nine cases). Family history of a neurological disorder was available in five patients. This study highlights the fact that calcification of basal ganglia and other parts of the brain is often a nonspecific finding on CT scan and it may not be possible to establish a clinicopathological correlation.

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.
