Opioid Overdose-Induced Diffusion Restriction in the Bilateral Basal Ganglia Revealed on Brain Imaging.

ABSTRACT

Opioid misuse and addiction have led to an opioid epidemic in the United States, with widespread effects on the healthcare system. Opioid-induced cardiovascular morbidity and mortality effects have been extensively described in past literature; however, neurological effects have been described less frequently.  Here, we describe a case of a female patient who presented to our center after being found unresponsive with magnetic resonance imaging (MRI), revealing bilateral basal ganglia diffuse restriction hyperintensities secondary to a diagnosis of opioid overdose.  Opioid overdose-induced bilateral basal ganglia diffusion restriction has only been described infrequently in the literature. Recognizing the associated imaging findings as a potential consequence of opioid overdose is important to avoid unnecessary workups for ischemic stroke.
