  • Title: Charles Bonnet Syndrome in a Patient With Right Medial Occipital Lobe Infarction: Epileptic or Deafferentation Phenomenon?
    Author: Kumral E, Uluakay A, Dönmez İ.
    Journal: Neurologist; 2015 Jul; 20(1):13-5. PubMed ID: 26185956.
    Abstract:
    BACKGROUND: Charles Bonnet syndrome (CBS) is an uncommon disorder characterized by complex and recurrent visual hallucinations in patients with visual pathway pathologic defects. OBJECTIVE: To describe a patient who experienced complex visual hallucinations following infarction in the right occipital lobe and epileptic seizure who was diagnosed as having CBS. PATIENT: A 65-year-old man presented acute ischemic stroke caused by artery to artery embolism involving the right occipital lobe. RESULTS: Following ischemic stroke, complex visual hallucinations in the left visual field not associated with loss of consciousness or delusion developed in the patient. Hallucinations persisted for >1 month and during hallucination, no electrographic seizures were recorded through 24 hours of videoelectroencephalographic monitoring. CONCLUSIONS: CBS may develop in a patient with occipital lobe infarction following an embolic event. CBS associated with medial occipital lobe infarction and epilepsy may coexist and reflects the abnormal functioning of an integrated neuronal network.
