Case presentation: A patient with Crohn's disease started an induction regimen with intravenous ustekinumab, and 2 months later he presented a left-sided pneumothorax. It had an atypical evolution that required surgical management. The medication was withdrawn and the pneumothorax resolved completely. One year later, he had a new flare-up of Crohn's disease and ustekinumab therapy was restarted, presenting a new episode of pneumothorax. Conclusion: To our knowledge, this is the first report of recurrent pneumothorax following two separate attempts to initiate ustekinumab. 2025-10-16T07:23:15Z 2025-10-16T07:23:15Z 2025 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Freixas Bermejo M, Riera Soler L, García Martínez L, Segarra Cantón O.
