Enteroenteric intussusception: CT findings in nine patients
AJR. American Journal of Roentgenology
|June 1, 1987
Summary
CT scans reveal three patterns of enteroenteric intussusception. Reniform masses indicate potential ischemia, suggesting urgent surgical intervention is needed for these specific findings.
Area of Science:
- Radiology
- Gastroenterology
- Surgical Pathology
Background:
- Enteroenteric intussusception is a condition where the intestine telescopes into itself.
- Accurate CT scan interpretation is crucial for timely diagnosis and management.
Purpose of the Study:
- To analyze CT scan patterns in enteroenteric intussusception.
- To correlate CT findings with clinical outcomes and the need for urgent surgery.
Main Methods:
- Retrospective analysis of CT scans from nine patients with confirmed enteroenteric intussusception.
- Review of associated small-bowel series and surgical findings.
- Histopathological examination of resected specimens.
Main Results:
- Three distinct CT patterns were identified: target lesion (5/9), reniform mass (2/9), and sausage-shaped mass (2/9).
- Patients with reniform masses showed focal ischemic changes and clinical signs of ischemia (acidosis, hyperamylasemia).
- Surgical confirmation of intussusception was obtained in seven patients.
Conclusions:
- CT scan patterns of enteroenteric intussusception vary, including target lesion, reniform mass, and sausage-shaped mass.
- The reniform configuration on CT is associated with focal ischemia and necessitates urgent surgical evaluation.
- Recognizing diverse CT presentations aids in appropriate and timely patient management.
