Extract

To the Editor: Peduncular hallucinosis (PH) is characterized, by among other symptoms, vivid, visual hallucinations (VH) that typically present in the initial days following an acute insult (i.e., vascular) to the pons, midbrain, cerebral peduncles, and/or thalamus.1 We present, with enthusiasm, a patient who developed symptoms consistent with PH status postthalamic/cerebral peduncle cerebrovascular accident.
