A 20-year-old female with burns (41% surface area) presented two months later with blurry vision, neurogenic bladder, weakness and new hypertension. Examination revealed bilateral cotton wool spots and macular edema. MRI showed non-enhancing, edematous lesions from the brainstem to the conus medullaris. Differential included demyelinating disease, acute disseminated encephalomyelitis and her final diagnosis PRES-SCI. Hydrocarbons inhalation causing myelin injury was unlikely 2 months post-burns. She received intravenous nicardipine and immunosuppression. 3 months later, her weakness and lesions resolved.
A total of 31 cases (mean age 20 years old) were reviewed from 2008-2021. All 32 patients, including our case, had elevated blood pressure (>140/80) and T2 hyperintense lesions spanning the brainstem to at least 4 segments of the spinal cord with unrevealing work up.
