Ileal lymphatic metastases from cecal carcinoma.
Involvement of the terminal ileum in cases of cecal carcinoma usually results from direct extension through the cecal wall and ileocecal valve. Extensive lymphatic metastasis from cecal carcinoma can result in deranged lymphatic flow and apparently cause metastatic involvement of the ileum and its mesentery in the absence of direct extension. Three cases with the lymphatic obstruction pattern are described. Demonstration of these changes on antegrade small bowel examination indicates that extensive lymphatic metastasis has occured and that resection will not be curative.
