Shrinking lung syndrome. A rare pulmonary manifestation of lupus: A case report

Abstract

Systemic lupus erythematosus (SLE) is an autoimmune disorder characterized by protean clinical manifestations. Shrinking lung syndrome (SLS) is a rare pulmonary complication of this disease. It is characterized by progressive dyspnea, pleuritic chest pain, and decreased lung volume without signs of parenchymal disease. We report the observation of a 71-year-old patient with systemic lupus for 46 years, whose SLS is evoked by unexplained chronic dyspnea, convincing imaging, and respiratory functional exploration.
