FIGURE 4. Borrmann type V lesions with multiple bone metastases. On endoscopic images, primary lesion is shown as scirrhous infiltration (arrows, a) accompanying some ulcerated areas (arrows, b). 18F-FDG demonstrates hot foci (arrows, c) corresponding to ulcerated areas. On images of bone scintigraphy, there are many hot spots corresponding to metastases on skull, scapula, vertebrae, costae, and sternum, but 18F-FDG PET image suggests bone metastases only in sternum (arrows, d) and part of scapula (arrow, e) and vertebrae (arrows, f).
