• Objective The purpose of our study was to evaluate the diagnostic value of serum galactomannan antigen (GM) testing combined with chest computed tomography (CT) of invasive pulmonary aspergillosis (IPA) in pediatric patients after hematopoietic stem cell transplantation. Methods A retrospective nested case‐control study was conducted in the identifying IPA among pediatric patients. Results A total of 141 eligible pediatric recipients with febrile neutropenia were enrolled in this study. All patients in the cases were diagnosed with proven‐probable IPA(PP‐IPA), while only 9 patients in the controls. GM testing was positive in 38 pediatric recipients in the cases and nine recipients in the controls with sensitivity of 62.3%, specificity of 81.8%. Among all patients with IPA, 46 patients in the cases and 9 patients in the controls had typical features of CT imaging with sensitivity of 79.3%, specificity of 85.2%. For discrimination of participants' GM testing combined with CT evaluation, the AUC of the diagnostic model was 0.887 with PPV of 0.764, and NPV of 0.872. Sensitivity was 0.793, and specificity was 0.852 in IPA. Conclusion The combination methods with serum GM and CT scan might be used as a valuable marker for early diagnosis of IPA in pediatric patients after HSCT.
