BACKGROUND Posterior reversible encephalopathy syndrome (PRES) is a poorly characterized and enigmatic syndrome. Despite consistently presenting with nervous system vasogenic edema, this malady has been associated with variable triggers, neurological symptoms, and natural history. CASE REPORT The report presents a 25-year old African American female who presented with altered mental status and bilateral cortical blindness. Neuroimaging identified vasogenic edema in the cerebellum, parietal lobe, and occipital lobe. Her PRES was associated with a hypertensive emergency, renal failure, and an atrial septum vegetation (culture-negative endocarditis). All 3 contributing etiologies were addressed, upon which the patient began to recover. During recovery, the patient experienced cerebral metamorphopsia, visualizing her entire environment in the form of a cartoon. After 2 weeks of treatment she recovered to baseline state of heath, with vasogenic edema resolved on follow-up neuroimaging. CONCLUSIONS This case presents a rarely catalogued phenomena during PRES recovery, cerebral metamorphopsia, along with a new potential association (culture negative atrial septum endocarditis). The report also highlights how PRES recovery patients (with cortical blindness) should be explicitly assessed for cerebral metamorphopsia and Charles Bonnet syndrome - which may distress patients. Lastly, the atypical presentation of cerebellar vasogenic edema in our patient validates existing literature that PRES does not have a uniform picture and is not well served by its current name or proposed diagnostic criteria. Therefore, renaming the disorder to reversible vasogenic edema syndrome and derestricting the diagnostic criteria, may prevent clinicians from being discouraged when faced with diagnosing PRES in the face of atypical findings.
