Primary familial brain calcification (PFBC), otherwise known as Fahr's disease, is a rare autosomal dominant condition with manifestations of movement disorders, neuropsychiatric symptoms, and epilepsy in a minority of PFBC patients. The clinical presentation of epilepsy in PFBC has not been described in detail. We present a paediatric patient with PFBC and refractory focal epilepsy based on seizure semiology and ictal EEG, but with generalized interictal EEG abnormalities. The patient was found to have a SLC20A2 mutation known to be pathogenic in PFBC, as well as a variant of unknown significance in SCN2A. This case demonstrates that the ictal EEG is important for accurately classifying epilepsy in affected subjects with PFBC. Further, epilepsy in PFBC may be a polygenic disorder.
