Question:

Findings that may be associated with intussusceptions on CT are all except:
1. Bowel-in- Bowel appearance
2. Invagination of mesenteric fat and vessels
3. Bowel wall thickening
4. Mural stratification
5. Dilated proximal bowel loops





Answer:

The correct answer for the question "Findings that may be associated with intussusceptions on CT are all except:" is:

4. Mural stratification



Explanation
Mural stratification is not a sign of intussusception. It is a nonspecific sign of pathology of the bowel wall can be seen with inflammatory, infective as well as ischemic etiologies. All the other options can be seen with intussusception. [The presence of an intraluminal soft tissue density within the bowel lumen- `the bowel within bowel` sign and presence of eccentric mesenteric fat and vessels are considered pathognomonic CT findings of intussusception]

Abstract
We report a rare clinical presentation of renal cell carcinoma in the form of small bowel obstruction which was secondary to a metastatic ileal intussusception. Intussusception in the elderly is most commonly due to an underlying neoplasm, however metastases from a renal cell carcinoma is very uncommon. We present clinical details, radiological and pathological findings of the case followed by a discussion of the diagnosis and management of intussusception in the adult population.
