case_images: (A) Vascular patterns can be found within the thickened mucosa. Ulcerative lesions present on the lesser curvature and anterior wall of the stomach, with multiple visible lymph node shadows in the vicinity. (B) The abdominal enhanced CT scan indicates a conspicuous thickening of the gastric wall in the gastric antrum region, measuring approximately 12.5 mm at its thickest point. (C) Coronal reconstruction of CT images.

case_images: Affiliated Hospital of Ningbo University, presenting with a two-month history of upper abdominal pain. An abdominal CT scan revealed significant thickening of the gastric wall in the antrum, accompanied by ulcers and multiple lymph nodes surrounding the stomach (Figure 1). After successfully completing six cycles of R-CHOP regimen (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy and achieving complete remission confirmed by FDG PET-CT (Figure S1), the patient underwent autologous hematopoietic stem cell transplantation on October 16, 2020.
case_images: The anterior wall of the stomach and the lesser curvature exhibit a sizable raised ulcer.

case_images: Subsequent endoscopic examination unveiled a substantial ulceration in the gastric antrum (Figure 2).
case_images: (A) Enlarged lymph nodes are visible in the left supraclavicular area, with the largest measuring approximately 23x14 mm. (B) No significantly enlarged lymph nodes were observed in the supraclavicular region after treatment.

case_images: An ultrasound examination identified several well-defined hypoechoic areas above the left clavicle, with the largest measuring approximately 23x14 mm (Figure 3). Post-treatment ultrasound examinations of superficial lymph nodes throughout the body indicated no enlargement above the clavicle, while the lymph nodes in other regions remained structurally unchanged and consistent in size with previous measurements (Figure 3).
