Figures & data
Figure 1. Endoscopic examination found two polypoid tumors with surface nodularity and ulceration at the (A) mid-body and (B) upper-body. (C) Microscopic features and (D) immunohistochemical staining revealed a low-grade B-cell MALToma.
Figure 2. (A) The projection view of FDG-PET showed a focal area with intense FDG uptake in the inner left upper quadrant of the abdomen. (B) Serial coronal views of the delayed images with distend stomach revealed two separate tumors. The SUVm of the lesions was 9.4 and 13.2, respectively.
Figure 3. (A) In the 6th month after therapy, a residual MALToma still existed in the biopsied tissue. (B) Projection view and (C) coronal views of FDG-PET failed to delineate the lesion. (D) FDG-PET remained negative in the 10th month after therapy.
