Calcifications of the basal ganglia in children with brain tumours.
Calcifications in the basal ganglia have been found in nine (5.4%) of all children treated for any kind of brain tumour in our department. This has occurred over a mean period of 2.8 years after diagnosis. The group of patients has been compared with a group of other children, matched for age, sex, histologic diagnosis and tumour treatment, but without calcifications of the basal ganglia. The groups differ from each other with respect to a significantly higher incidence of hypothyroidism and growth hormone deficiency in the group of children with calcifications in the basal ganglia. Moreover the children with calcifications show a larger IQ-loss. Although the pathogenesis of the calcifications of the basal ganglia is not known, an association of damage to the vascular bed of the basal ganglia due to periods of increased intracranial pressure, together with endocrine deficiencies is discussed. We advise an adequate supplementation in cases of endocrine deficiencies in children treated for brain tumours as early as possible.
