Suspected fibrin glue‐induced acute eosinophilic pneumonia after pulmonary resection: A case report

Abstract

Abstract Air leakage is a common complication after pulmonary resection, and fibrin glue is used as a sealant to reduce postoperative air leakage. It is generally recognized that fibrin glue‐induced adverse events are rare. Herein, we report a rare case of suspected fibrin glue‐induced acute eosinophilic pneumonia (AEP). A 72‐year‐old man underwent right lower lobectomy and mediastinal lymph node dissection for right lower lung cancer. Fibrin glue was sprayed to cover the interlobar surface of the right upper and middle lobes. On postoperative day 10, computed tomography (CT) revealed ground‐glass shadows around the interlobar surface of the remaining lobes of the right lung. Although antibacterial drugs were administered for suspected bacterial pneumonia, fever spike, shortness of breath, and exacerbation of ground‐glass shadows were observed. Peripheral blood and bronchoalveolar lavage fluid showed increased eosinophil count, supporting the diagnosis of AEP. Pneumonia resolved after prednisolone administration. At one‐year follow‐up, CT showed no AEP recurrence. Drug‐induced pneumonia usually develops in the bilateral lung and rarely in the hemilateral lung. In this case, pneumonia was localized around the site covered with fibrin glue, suggesting fibrin glue‐induced AEP. Thus, the use of fibrin glue should be carefully considered during pulmonary resection.
