Background:
We describe the presentation of a young woman with long-standing complex partial seizures with occasional secondary generalization, who presented with complex visual hallucinations (CVHs) and delusions.
Methods:
Routine biological workup including magnetic resonance imaging revealed an area of significant left-sided occipital gliosis. Video telemetry monitoring revealed a left occipital focus for the origin of the electrographic seizure discharge.
Conclusion:
CVHs occur in a range of organic states, including epilepsy, and can be understood in terms of the underpinning neuroanatomy and neurotransmitter systems of the visual system.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
