From: Two cases of granuloma mimicking local recurrence after pulmonary segmentectomy
a Case 1: CT scan shows a nodule measuring 25 × 22 mm in the residual left lower lobe. b PET/CT revealed FDG uptake in the nodule (SUVmax: 5.3). c Microscopic view showing hyperplasia of collagen fibers (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 alveolar epithelium (× 200)
