Abstract:
We report a 68-year-old woman who experienced visual hallucinations diagnosed as peduncular hallucinosis (PH) following microvascular decompression for trigeminal neuralgia. Postoperative MRI showed only ischemic oedema of the left cerebellar hemisphere due to retraction. Our case first reveals that PH can be induced without direct brainstem injury, instead possibly by a cerebellar lesion.
