Acute rejection after lung transplantation: association between histopathological and CT findings

Research output: Contribution to journalArticlepeer-review


Purpose: To evaluate the predictive role of computed tomography (CT) on acute rejection in patients who underwent lung transplantation (LT). Materials and methods: Seventy-eight patients who underwent LT were evaluated in our study. The CT scans were reviewed by three different radiologists, who evaluated the findings potentially associated with acute rejection such as air trapping, tree-in-bud, consolidations, crazy paving, ground-glass opacity, bronchiectasis, thickening of intralobular or interlobular septa and presence of pleural effusion. The association between a tissue diagnosis of acute rejection and the above-mentioned CT findings was assessed using a multivariate model of logistic regression. Results: Based on our results, none of the CT findings included in the study, alone or in combination, showed significant statistical association with the diagnosis of acute rejection. Conclusion: CT is a very useful technique for the assessment of lung transplant recipients although it has limited accuracy for the assessment of acute rejection. None of the radiological findings considered in our study was significantly associated with histologically proven acute rejection.
