AbstractCommon variable immunodeficiency (CVID) causes granulomatous-lymphocytic interstitial lung disease (GLILD) and has a poor prognosis. We herein report a case of GLILD in a 49-year-old woman with CTLA-4 deficiency-associated CVID. The patient presented with dyspnea that had worsened over the past two years. A laboratory examination revealed hypoglobulinemia and pancytopenia. Chest computed tomography showed diffuse infiltrative and granular shadows in the bilateral interstitium. A flow cytometric analysis of blood cells and genetic testing confirmed CTLA-4 deficiency. We performed video-assisted thoracoscopic surgery for the pathological diagnosis of GLILD and to exclude infection and malignancy. Corticosteroid treatment successfully improved the condition of the patient.
