case_images: The chest computed tomography imaging at admission showed diffuse inflammation in both lungs. (A) Transverse image, showing markedly thickened, disorganized, and blurred pulmonary markings, with some areas presenting a reticular and honeycomb-like appearance. (B) Coronal image, showing diffuse patchy areas of increased density in both lungs with indistinct borders.

case_images: T cell count of 168 cell/mul (normal range, 238-1,250 cell/mul), and CD3+ T cell count of 420 cell/mul (normal range, 770-2,860 cell/mul), indicating severe cellular immunodeficiency. Chest CT revealed diffuse pulmonary inflammation with a small amount of pleural effusion (Figures 1A,B). Considering that the patient had been on long-term steroid therapy, and Cellular immunity chip testing showed decreased levels of CD3, CD4, and CD8, which indicate cellular immunodeficiency and an increased propensity for infectious diseases, the patient was considered the possibility of pneumonia. Then a combination of Meropenem (1 g iv
