Overview

Case Presentation

A 44-year-old female patient was admitted to the psychiatric ward with complaints of self-referent, mystical delusions and confusion.

  • She was irregular in attending the follow-up neurology appointments and had poor compliance to antiepileptic therapy.
  • Ancillary tests undergone during a previous hospitalization had reported a focal slowing activity in the left frontotemporal topography on electroencephalogram and a 
  • right cortico-subcortical parieto-occipital lesion of encephalomalacia on magnetic resonance imaging.
