摘要：

We report the case of a 4-year-old child who experienced rapid neurological decline following opioid administration during anesthesia for an interventional procedure to treat a vein of Galen aneurysm. Cerebral magnetic resonance imaging (MRI) revealed marked cytotoxic edema in both cerebellar hemispheres and the brainstem, indicative of opioid-induced neurotoxicity. A follow-up MRI, performed 2 weeks later, showed profound cerebellar and brainstem atrophy and showed reduction in mass effect due to cytotoxic edema. Teaching point: Pediatric opioid-use-associated neurotoxicity with cerebellar edema (POUNCE) syndrome is a rare condition, characterized by cerebellar edema as a hallmark feature, which can be identified on MRI in pediatric patients following opioid use.
