Complex visual hallucinations as the sole manifestation of symptomatic temporo-occipital lobe epilepsy due to old intracerebral hemorrhage

Complex visual hallucinations in a blinded visual field are an under-appreciated phenomenon. Both a stimulating phenomenon and a release phenomenon have been suggested as explanations for these hallucinations. However, the mechanisms of complex visual hallucinations in patients with visual field defects due to intracranial diseases are still controversial. A patient with complex visual hallucinations in a quadrantanopic visual field caused by symptomatic epilepsy after cerebral hemorrhage is reported.
