Summary
A 70-year-old man underwent right upper lobectomy for lung adenocarcinoma.During the operation, hemostatic matrix (as known Floseal ® ) was used to prevent pulmonary laceration-associated bleeding.When 18 F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography was performed for staging after surgery, intense 18 F-FDG uptake was observed in the cicatricial fibrotic tissue in the operation area, and no significant change was observed in that area during the 4-year follow-up.Because it remained stable for several years without treatment, this finding was thought to be due to a foreign body reaction caused by the homeostatic material.
