Abstract |
PURPOSE To report a case of Charles Bonnet syndrome that developed after resection of a meningioma. CASE SUMMARY: The authors reviewed the medical record, brain magnetic resonance image, and Goldmann visual field test of a 56-year-old male patient who was diagnosed with a meningioma in the right parietal and occipital lobe and underwent resection of the tumor. The preoperative Goldmann visual field test showed homonymous left inferior quadrantanopsia. Subtotal resection of the mass in the right parietal and occipital lobe was performed, and postoperative histopathologic examination confirmed the diagnosis of a meningioma. Postoperatively, the patient complained of visual hallucination in an area of the eye with visual field defects. However, his consciousness and orientations were intact, and other cognitive functions were also normal. CONCLUSIONS: Visual hallucination can manifest in an area with visual field defects after resection of abrain tumor. In such a case, a diagnosis of Charles Bonnet syndrome should be considered. |
