| Popis: | Introduction Recognition of severe forms of posterior reversible encephalopathy syndrome (PRES) has improved. Management of these patients remains challenging, particularly in patients with the combination of edema and hemorrhage. Methods A prospective inpatient neuro-intensive care database was queried for patients with PRES. Malignant PRES was diagnosed by clinical assessments (GCS less than 8 and clinical decline despite standard medical management for elevated intracranial pressure) and radiographic criteria (edema with associated mass effect; brain hemorrhage exerting mass effect; effacement of basal cisterns, transtentorial, tonsillar, or uncal herniation). Malignant PRES was defined as: radiology studies consistent with PRES; GCS less than 8; and clinical decline despite standard elevated intracranial pressure management. Results Five cases were identified over a 4 year interval. The following contributing conditions were also present: chemotherapy (1), systemic lupus erythematosis (2), pregnancy (1), and methamphetamines (1). Neurocritical care interventions included: hyperosmolar therapy (5), anticonvulsants (5), management of coagulopathy (5), and ventilatory support (5). Neurosurgical interventions included: craniectomy (5), hematoma evacuation (3), and external ventricular drain (4). Brain biopsy was performed in 5 patients and was negative for vasculitis, demyelinating disease, tumor, or infection. Cyclophosphamide was administered to the two patients with SLE. With long-term follow up, all patients achieved good functional outcomes (modified Rankin score 1–2). Conclusion In contrast to historical reports of high mortality rates (16–29%) for severe and hemorrhagic PRES variants, we had no fatalities and observed favorable functional outcomes with intracranial pressure monitoring and craniectomy for malignant PRES cases who fail medical ICP management. |
