A CASE OF LOW GRADE INTUSSUSCEPTION OF THE ILEUM DUE TO MALIGNANT LYMPHOMA OBSERVED WITH COLONOSCOPY

Abstract

A 74 year-old waman was referred to Tenri hospital with the diagnosis of a tumor of the ileocecal region. She complained of right hypogastralgia for two months and a tumor of the terminal ileum was pointed out by small bowel enema by a home doctor. Colono-scopic examination revealed a round mass which moved to-and-fro through the ileocecal valve. The tumor was diagnosed as malignant lymphoma by biposy. Garium scintigram demonstrated swelling of the regional lymphnodes in addition to the tumor and was useful in determining the clinical stage preoperatively. Resection of the ileocecal segment was performed. The tumor was diagnosed as B cell malignant lymphoma, diffuse, large cell type, histologically. This is an uncommon case of low grade intussusception of the ileum due to malignant lymphoma observed with colonoscopy.
