Abstract
Posterior reversible encephalopathy syndrome (PRES) represents an acute neurological complication, characterized by diverse symptoms (headache, visual disturbances, altered mental state, seizures, or other focal deficits) that usually relate to uncontrolled arterial hypertension (HT), eclampsia, sepsis, renal disease, autoimmune disorders, or cytotoxic medication. The accurate diagnosis relies on radiological features, commonly displaying parieto-occipital vasogenic edema. We report a particular case of PRES involving the brainstem and capsular-thalamic regions in a patient with systemic lupus erythematosus (SLE). A 25-year-old female, with a 5-year history of SLE with several manifestations (HT, seizures, lupus nephritis, pericarditis), was admitted for sudden onset of impaired consciousness and double vision. She was on maintenance immunosuppression, hydroxychloroquine, and antihypertensive and antiepileptic medication, denying any illicit drug intake or recent infections. The clinical exam revealed elevated blood pressure, altered mental state, left hemiparesis, bilateral pyramidal signs, ataxia, strabismus, and left facial palsy, with no meningeal signs or fever. The initial brain CT scan showed diffuse hypodense aspect of the pons, mesencephalon, and capsular-thalamic regions, confirmed by the MRI exam, displaying extensive hyper-T2-weighted lesions in the same areas, associating petechial hemorrhages and restricted diffusion. The laboratory work-up excluded infectious encephalitis, vasculitis, or other metabolic complications, and the favorable clinical-radiological remission confirmed the diagnosis of PRES. We conducted a literature review regarding PRES in SLE, with special focus on imagistic presentation and major complications. PRES may complicate the evolution of SLE associated with HT, renal dysfunction, or immunosuppression. Neurologists and radiologists should be aware of atypical imagistic patterns and hemorrhagic complications in PRES, as timely recognition is essential.
