A 25-year-old woman with recurrent syncopal episodes presented with a first time generalized tonic clonic (GTC) seizure. She had experienced two prior fainting spells lasting seconds and associated with diet pills and dehydration. She had another similar spell prior to falling, sustaining a laceration to the right posterior occiput, and having a witnessed GTC seizure. Her scalp electroencephalography (EEG) showed left temporal slowing with sharp features. T1-weighted and T2-weighted MRI revealed two moderately enhancing focal lesions within the left frontal and temporal regions. These findings raised the possibility of an underlying seizure focus. Repeat imaging studies of this patient 1 month later, however, demonstrated resolution of these findings and an area of encephalomalacia, consistent with a traumatic coup contrecoup injury. A repeat EEG was normal. Therefore, the cause of the loss of consciousness was due to syncope with the consequent head injury giving rise to an isolated seizure. Understanding the underlying cause of a seizure is important in dictating treatment. In this setting the patient was not initiated on seizure medication and has done well.
