Systemic lupus erythematosus (SLE) is a persistent autoimmune disorder that manifests across a spectrum ranging from mild to severe disease, often requiring hospitalization and critical care management. We present a severe case of systemic involvement at its onset. A young woman, with a background of arterial hypertension, presented to the emergency department exhibiting a total anterior circulation stroke and exuberant symmetric lower limb edema. Her condition rapidly deteriorated with neurological impairment, respiratory failure requiring mechanical ventilation, and acute kidney injury prompting her admission to the ICU. Following clinical investigation, a diagnosis of SLE was established, according to the European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) 2019 and Systemic Lupus International Collaborating Clinics (SLICC) 2012 classification criteria. The patient underwent treatment involving high-dose corticosteroids, followed by the Euro-Lupus protocol, resulting in significant improvement, despite her severe neurological deficit at admission. Lupus is a complex disease that is often difficult to diagnose because of its potential to mimic various other conditions. Our report delves into a case of previously undiagnosed lupus leading the patient to the ICU. The clinical scenario described adds valuable insights to the understanding of lupus-related complications and their management through a multidisciplinary approach.
