Hippocampal and Cerebellar Involvement in Opioid-Associated Amnestic Syndrome: A Unique Case Report

We present a case of opioid-associated amnestic syndrome (OAS) in a 46-year-old female with persistent acute anterograde amnesia and biochemically confirmed with fentanyl use. The brain Magnetic Resonance Imaging (MRI) examination demonstrated symmetric restricted diffusion and T2/fluid-attenuated i...

Sumario:We present a case of opioid-associated amnestic syndrome (OAS) in a 46-year-old female with persistent acute anterograde amnesia and biochemically confirmed with fentanyl use. The brain Magnetic Resonance Imaging (MRI) examination demonstrated symmetric restricted diffusion and T2/fluid-attenuated inversion recovery (FLAIR) hyperintensities in the hippocampi and cerebellum. While cases of cerebellar findings in OAS are rare in the literature, this is a unique case with corresponding images that demonstrate cerebellar involvement in addition to the more common hippocampal finding.
