Cerebral aneurysms secondary to cerebral vasculitis related to systemic lupus erythematosus are rare. We report a 31-year-old woman who presented with a lupus flare associated with inaugural generalized seizures. Computed tomography angiography showed subarachnoid hemorrhage by rupture of a cerebellar artery fusiform aneurysm. Later, despite the initiation of corticosteroids and cyclophosphamide, she presented a second cerebral hemorrhage due to the rupture of a new aneurysm in lenticulostriates arteries. The outcome was fatal. We discuss the frequency and management of this severe complication of systemic lupus erythematosus., (Copyright © 2011 Société nationale française de médecine interne (SNFMI).

Introduction: Posterior reversible encephalopathy syndrome is a clinico-radiological entity characterized by neurologic symptoms in association with usually reversible bilateral posterior hemispheric oedema on neuroimaging. Many pathological conditions and treatments have been associated with this syndrome., Case Report: We report a 19-year-old woman, followed-up for hypocomplementemic urticarial vasculitis, who presented with a posterior reversible encephalopathy syndrome induced by the intake of an over-the-counter cold remedy containing pseudoephedrine. Clinical manifestations and radiological abnormalities resolved after anti-hypertensive therapy and withdrawal of sympathomimetic drug., Conclusion: The diagnosis of posterior reversible encephalopathy syndrome should be considered in patients with compatible clinical and radiological presentation because of its potential reversibility with an appropriate management. Intake of drugs, including over-the-counter cough and cold drugs, should be looked for in the history as well as autoimmune disorders., (Copyright 2010 Société nationale française de médecine interne (SNFMI).
