The CT scan demonstrates:
- huge ileocolic intussusception with the lead point from the ileum in the mid transverse colon
- intraluminal solid/cystic mass acting as the lead point for the intussusception, measuring 11.5 x 6.8 x 6.2 cm with a heterogeneous enhancement of the solid component
- dilatation of the proximal portion of the terminal ileum with feces sign
- No dilatation of the rest of the small bowel loops
- distended thin-walled appendix with fluid-filled well-visualized on reconstructed images
- minimal effusion in Douglas pouch
Case Discussion
CT features of an ileocolic intussusception with intraluminal mass. Colonoscopy with biopsy was performed confirming the diagnosis of non-Hodgkin lymphoma (NHL)
The most common causes in adults are the GIT neoplasms:
- colorectal carcinoma (most common)
- small bowel lymphoma/Burkitt lymphoma
- carcinoid tumors
- GIST
- metastases, e.g. malignant melanoma, breast cancer, lung cancer
