Cocaine abuse is a well known cause of cerebrovascular complications. An inflammatory vasculopathy hypothesis has been proposed, but the medical literature has only reported a few pathological confirmations. We report a case with a biopsy demonstrating cerebral inflammatory vascular changes that are associated with cocaine abuse. A 21‐year‐old male, a twice weekly cocaine abuser, developed encephalopathy, apraxia and left hemiparesis with hemisensory loss during the first week after his last cocaine intake; postural tremor and dystonia appeared later. Laboratory data were unrevealing. Cerebral angiography showed a lack of vascularization in the left precentral and central arterial groups. A corticomeningeal cerebral biopsy demonstrated perivascular cell collection and transmural lymphomonocytic infiltration of the small cortical vessels. All symptoms improved with corticosteroid treatment, but 4 years later, the patient returned with a worsening of his encephalopathy and a severe memory impairment, emotional lability and apraxia. A cerebral magnetic resonance image (MRI) showed subcortical and periventricular lesions suggesting ischemic damage in small‐size vessel areas as well as cortical atrophy. This new case supports the existence of an encephalopathy associated with vascular inflammatory changes in a cocaine abuser, although more clinical and experimental data are necessary to define its physiopathology.
