(en) [Effect of surgery of pulmonary cysts related to immunoglobulin light chain deposits] INTRODUCTION: Light chain deposition disease is a rare anatomo-clinical disorder, which rarely leads to cystic lung destruction. CASE REPORT: We report the case of a 62years old female patient with a history of a monoclonal gammopathy of unknown significance who developed progressive dyspnea. Thoracic CT-scan demonstrated a diffuse pulmonary cystic disorder with predominance in the right lower lobe. Thoracoscopic surgical resection of that lobe led to a diagnosis of non-amyloid kappa light chain deposits. Surgery also resulted in a lung volume reduction effect with clinical and functional benefits related to improved ventilation of adjacent segments. CONCLUSION: This report of pulmonary cystic disorder related to a light chain deposition disease highlights the potential clinical and functional benefits observed after lung volume reduction surgery.
