Abstract

Idiopathic basal ganglia calcification (IBGC), also known as Fahr disease, is a rare neurodegenerative disorder characterized by the accumulation of extensive parenchymal and vascular calcifications in the basal ganglia, with variable calcifications elsewhere in the brain. Typically, IBGC presents with neurologic and psychiatric symptoms in middle-aged adults. Recent genetic studies have identified alterations in 4 genes causing IBGC, including alterations in SLC20A2 on chromosome 8p11.2. Currently, there are no clinical descriptions of patients with IBGC occurring within the context of a complex genetic syndrome. Here, we present a case of pediatric 8p11 deletion with IBGC, hereditary spherocytosis, vitreoretinopathy, and focal cortical dysplasia. We review multiple cases of IBGC with pediatric onset due to SLC20A2 deletion in the literature, and raise the consideration of IBGC in the evaluation of pediatric patients with 8p11.2 deletion syndromes.
