Abstract
A 26-year-old woman with known common variable immunodeficiency was referred for FDG PET/CT because of interstitial pulmonary abnormalities and enlarged mediastinal and hilar lymph nodes. FDG PET showed a combination of ground-glass abnormalities and pulmonary nodules, both displaying increased FDG uptake. In addition, multiple FDG-avid axillary, mediastinal, hilar, and inguinal lymph nodes were found. The abnormalities were diagnosed as granulomatous-lymphocytic interstitial lung disease. Cytology of mediastinal lymph nodes yielded only benign disease, without further specification, whereas histology of an excised axillary lymph node showed reactive changes, but no malignancy.
