%X Severe lupus pneumonitis is a rare and life-threatening complication of systemic lupus erythematosus (SLE), characterized by its rapid progression and high mortality rate. This case report describes the clinical trajectory and therapeutic management of a young Aboriginal female with established lupus nephritis who developed severe lupus pneumonitis. Despite her stable renal condition under long-term immunosuppressive treatment, she experienced acute respiratory distress, leading to her admission to the intensive care unit and subsequent mechanical ventilation. The diagnostic process was complicated by the difficulty in obtaining tissue biopsies, necessitating reliance on clinical judgement and radiological evidence to formulate a diagnosis. The patient was treated with pulsed intravenous methylprednisolone followed by rituximab infusions, resulting in significant clinical and radiological improvement. This case highlights the importance of early and intensive immunosuppressive therapy in the management of severe lupus pneumonitis and underscores the utility of a multidisciplinary approach in overcoming diagnostic ambiguities. Furthermore, it contributes to the growing body of evidence supporting the efficacy of rituximab in severe lupus pneumonitis cases, offering insights into potential therapeutic avenues when conventional management strategies are inadequate or unsuitable.
