The authors present the case of a 25-year-old individual who presented acutely following a generalised tonic-clonic seizure. Brain MRI of the individual demonstrated the classical appearance of multiple cerebral cavernous haemangiomas (cavernomas). There was an autosomal dominant family history. Genetic testing identified a truncating mutation in the KRIT1 gene in the individual and confirmed the diagnosis of familial cerebral cavernomas as the cause of epilepsy in the family.
