Life Threatening Pneumonia in Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease characterized by multisystem involvement. Pulmonary manifestation of SLE varies from pleuritis to severe parenchymal involvement as pneumonitis mimiking as acute respiratory distress syndrome (ARDS). Other pulmonary manifestations of SLE include pulmonary artery hypertension, diffuse alveolar haemorrhage, pulmonary embolism, acute reversible hypoxaemia, and shrinking lung syndrome. We present the case report of a young woman who presented with severe lupus pneumonitis with central nervous system and renal involvement.
