Abstract:

Posterior reversible encephalopathy syndrome ( PRES ) is a rare disorder , associated with a variety of medical conditions and certain treatments . It is characterized by edematous injuries mainly within the posterior cerebral white matter , and it is generally reversible by treating the underlying condition . Common symptoms are headaches , altered consciousness , and vision loss . It is usually associated with malignant hypertension , pregnancy toxemia or use of immunosuppressive agents . We describe the case of an HIV - positive patient in the context of increased blood pressure after cocaine use . PRES was diagnosed through imaging studies , and both infectious and neoplastic causes were discarded . Cocaine use was discontinued , and the patient was treated with a type ii angiotensin receptor antagonist , which allowed blood pressure control and complete reversal of symptoms .
