A 67-year-old female was admitted with diarrhea. Preoperatively, we di
agnosed intussusception due to malignant lymphoma in the ileocecal reg
ion by image and colonoscopic examinations. We resected the right hemi
colon for the tumor, which was located mainly in the cecum, causing in
tussusception. The stenotic terminal ileum free of the tumor was invag
inated within the cecum with infiltrating tumor, thus showing the appe
arance of an anthill. The growth of the tumor corresponded with Wood's
constrictive type, in which intussusception rarely occurs.
