Abstract
The problem of intracranial calcifications in children has not been widely discussed in the literature yet. The aim of this study is to emphasise different clinical aspects of intracranial calcifications found in subcortical nuclei and cerebellum in children with disturbed calcium metabolism. We report three different cases of hypoparathyroidism in children in whom similar radiological changes on computed tomography (CT) of the brain were found. An 11-year-old boy was referred to us after episode of tetany. We confirmed the diagnosis of idiopatic hypoparatyhyroidism (presence of Chvostek and Trousseau signs, hypocalcemia, hyperphosphatemia, low parathormone serum concentration). On brain CT small, symmetric calacifications in the subcortical nuclei and frontal lobes were imaged. A diagnosis of pseudohypoparathyroidism type Ib in 10-year-old girl was established on the basis of clinical symptoms (syncope with seizures, recurrent carpopedal spasms in the past) and laboratory investigations (hypocalcemia, hyperphosphatemia, high parathormone serum concentration). In 11-year-old girl autoimmune polyglandular syndrome type I was diagnosed (hypoparathyroidism with chronic mucocutaneous candidiasis and nail dystrophy from the age of 2). CT of the brain showed multiple irregular symmetric calcifications in cerebellar hemispheres, internal capsula and subcortical nuclei on the border of white and grey matter in both frontal lobes.
