Cocaine-Induced Toxic Leukoencephalopathy: A Case Report.

Cocaine is a widely abused controlled substance. Cocaine use is associated with a myriad of side effects and a sequelae of consequences secondary to its harmful nature and potential adulterants, the most recently described and less known sequelae being leukoencephalopathy. In our case, we describe a 58-year-old male who presented to the ED with agitation and acute stroke-like symptoms with reported rapid onset. Cocaine induced toxic leukoencephalopathy is a diagnosis of exclusion, thus other etiologies of disease were ruled out in a full neurological and infectious workup; most importantly consisting of extensive brain imaging, alluding to the diagnosis of acute cocaine induced toxic leukoencephalopathy in an individual with a confirmed history of cocaine and cannabinoid abuse. Although there is no targeted therapy for the condition to our knowledge, we utilized a supportive approach to treatment in contrast to other reported treatment modalities which included the use of steroids, plasma exchange, and intravenous immunoglobulin. Furthermore, we describe the clinical evaluation and treatment throughout the patient's hospital course with his eventual marked improvement from initial presentation.
