Positron emission tomography (PET) and computed tomography (CT) revealed new nodules with abnormal uptake in the remaining lobes; they were found to be benign lesions. In the first case, the new nodule reduced during the clinical course of the patient. In the second case, completion lobectomy was performed as the intraoperative frozen section diagnosis was malignancy three years after the segmentectomy. These cases suggest that oncologist should consider the possibility of benign lesions mimicking local recurrence in the remaining lobes after segmentectomy for lung cancer.}
