He was able to conduct his activities of daily living at baseline; however, his condition declined over a period of months to the point of shortness of breath with climbing a flight of stairs. The patient also developed a frequent dry cough and wheezing. He denied fever, chest pain, weight loss, and hemoptysis. He had been diagnosed with CVID in 1968, at 7 years of age, after recurrent episodes of bronchitis and pneumonia, and was treated with IV immunoglobulin monthly for decades. The patient was a lifelong nonsmoker and had no significant environmental or occupational exposures. He was referred to our hospital for further management.Mahidol UniversityMedicineArticleSCOPUS10.1016/j.chest.2017.11.034
