Abstract

Visual hallucinations may occur in association with damage to any part of the visual pathway. Charles Bonnet syndrome (CBS) is characterized by vivid visual hallucinations caused by injury to the visual system, while other cognitive functions are preserved. We report on the clinical and neuro-imaging findings of two patients with CBS after acute stroke. The lesions were located bilaterally in the occipital lobes of both patients, although the lesion in patient 1 extended beyond the occipital lobe. In patient 1, moving hallucinations persisted for 9 months after symptom onset, while in patient 2, static hallucinations completely disappeared 7 days after the first hallucination. The latter case had a more extensive lesion on brain magnetic resonance imaging. Our cases suggest that the clinical course of CBS is variable irrespective of cortical lesion size, although this must be confirmed with more patients in the future.
