A 71-year old retired man had no prior history of psychiatric or neurological problems. While at home with his two sons, daughter, and wife, he suddenly experienced weakness in all four extremities and started seeing policemen entering the front door of his house. He became irritable and fearful that the police would take him away. He was brought to the emergency room (ER). A neurological examination was normal, and the hallucinations ceased. The patient was released with follow-up at the psychiatry clinic. Three days later he was brought to the ER completely comatose due to a brainstem stroke. In retrospect, patient's attack was found to be a brainstem transient ischemic attack (TIA), which caused him to experience peduncular hallucinosis.
