Images at various time points during treatment. (A) PET image suggested the abnormal manifestations of the body before treatment. (B) Reexamination of ECT after right hemicolectomy and splenectomy. (C) PET image suggested that complete response (CR) achieved after five cycles of chemotherapy.

PET-CT (Figure 1C) (29 December, 2018) demonstrated there was no increase in the glucose metabolism in the operation area.
Pathologic findings in splenectomy and right hemicolectomy specimens. (A) Postoperative splenic pathology showed chronic splenic congestion (H&E, magnification x 100). (B) Right hemicolon pathology indicated lymphoproliferative lesions, which were considered to be hematological diseases (H&E, magnification x 40).

The results of enteroscopy before and after chemotherapy (A) huge ulcers could be seen in the ileocecum and rectum at the 4cm of the anal entrance (B) ulcers in the terminal ileum, multiple ulcers and polyps of the colon.

Enteroscopy on 19 November, 2018 indicated there were ulcers in the terminal ileum, multiple ulcers and polyps of the colon (shown in Figure 3B).
Pathological changes of intestinal tract before and after chemotherapy. (A) The intestinal pathological examination before chemotherapy showed inflammation of mucosa with proliferation of local granulation tissue in the ileocecal region and rectum (H&E, magnification x 100). (B) Reexamination of enteroscopy after four cycles of chemotherapy, pathological manifestation was inflammation of ileal terminal mucosa, ascending colon mucosa and rectal mucosa, accompanied by rectal granulation tissue proliferation (H&E, magnification x 100).
