AB Dextromethorphan toxicity in young children (especially those with age 4 years or younger) can have an extremely poor prognosis if untreated. However, if timely recognized and optimally managed, it can have a good clinical outcome despite significant initial insult. We present 3 pediatric cases (&lt; 5 years old) with sudden unresponsiveness following ingestion of cough medications containing dextromethorphan. All these children showed cytotoxic edema in cerebellar hemispheres on MR brain, with diffusion restricting foci in supratentorial white matter in 2 patients. These features resemble the recently described acute opioid toxidrome in children, the POUNCE syndrome (Pediatric Opioid Use-associated Neurotoxicity with Cerebellar Edema). Hence, we name this entity “DANCE” (Dextromethorphan Associated Neurotoxicity with Cerebellar Edema) to increase the awareness of dextromethorphan toxicity in young children and the need to promptly recognize it to initiate optimal management.ABBREVIATIONS: POUNCE= Pediatric Opioid Use-associated Neurotoxicity with Cerebellar Edema; DANCE= Dextromethorphan Associated Neurotoxicity with Cerebellar Edema
