Cytotoxic lesion of the splenium of the corpus callosum in a patient with EVALI

Since first recognized in July 2019, numerous cases of a lung illness associated with electronic-cigarette use or vaping particularly tetrahydrocannabinol in adolescents and adults have been reported. As of January 2020, the Center for Disease Control has reported over 2500 cases of electronic-cigarette or vaping product use-associated lung injury (EVALI), including 60 deaths. Affected patients most commonly present with respiratory or gastrointestinal complaints although neurological symptoms including headache, confusion and lethargy have been reported. We present a new as yet unpublished finding in the brain of a previously healthy teenage boy with EVALI. Brain imaging may be warranted in this patient population.
