Shrinking lung syndrome caused by systemic lupus erythematosus: A case report

Shrinking lung syndrome (SLS) is a rare manifestation of systemic lupus erythematosus (SLE), characterized by dyspnea, pleuritic chest pain, diaphragmatic elevation, and decreased lung volumes. We describe a lupus patient who presented with dyspnea. In addition, she had characteristic chest imaging findings of small lung volumes, elevated left hemidiaphragm, and thinning of the diaphragmatic crura.
