From: Two cases of granuloma mimicking local recurrence after pulmonary segmentectomy
a Case 2: CT scan shows a nodule in the residual right upper lobe. b PET/CT revealed FDG uptake in the nodule (SUVmax: 6.8). c Microscopic view showing fibrous scars (hematoxylin and eosin staining, original magnification × 100). d Granulomatous nodules with foreign-body giant cells (× 400). e Immunohistochemistry showing no CEA-positive cells in the granuloma despite CEA-positive secretion (× 200)
