Abstract
Intussusception caused by a tumor of the small intestine is a rare disease. This paper describes a patient witn malignant lymphoma of the ileum causing intussusception who was admitted to the hospital because of ileus and was diagnosed as intussusception by CT and ultrasonography, leading to operation. A 73-year-old man complaining of abdominal pain and a weight loss was admitted for ileus. Conservative therapy failed to improve the patient's condition. CT scan and ultrasonography revealed intussusception of the distal ileum. Using GastrografinTM, an enema reduction was temporarily sustained. A polyp-like mass, 8cm in diameter, was detected in the ascending colon. As the ileus condition persisted, right hemicolectomy was carried out 3 days later. A 6×5×4cm tumor was found in the distal ileum. Histologically it was malignant lymphoma. CT scan and ultrasonography are useful diagnostic methods for intussusception. A possibility of malignant tumor should be suspected in adult cases of intussusception.
