Abstract
We report three adult cases of malignant lymphoma with intussusception diagnosed before the surgery. All cases care to our unit complaining of intermitted abdominal pain. Barium enema studies showed characteristically the large tumor, crabclaw-like findings and coiled-spring sign. They were diagnosed as intussusception resulting from the advanced portion of tumor. Colonoscopic findings demonstrated a ball-like tumor with rough, lustrous and lack of hemorrhagic surface, which occupied a lumen. These findings differed from usual epithelial tumor, especially a malignant lymphoma, was strongly suspected. Malignant lymphoma was diagnosed from biopsy specimens. The sites of original tumors, which were confirmed histopathologically, were the terminal ileum, ileocecal valve and cecum. These cases of intussusception occurring at the anal side of Bauhin's valve were very rare and the endoscopic findings were very specific.
