Summary

Computed tomographic (CT) imaging reveals key signs of intussusception, including a target mass and bowel wall thickening. Advanced stages show signs of obstruction and potential vascular compromise, crucial for diagnosis.

Area of Science:

Radiology
Pediatric Imaging
Gastrointestinal Imaging

Background:

Intussusception is a common cause of bowel obstruction in children.
Accurate diagnosis relies on characteristic imaging findings.

Purpose of the Study:

To describe the computed tomographic (CT) findings associated with intussusception.
To correlate CT features with the progression and severity of the condition.

Main Methods:

Review of computed tomographic (CT) scans from patients diagnosed with intussusception.
Analysis of imaging features such as target mass, bowel wall thickening, and mesenteric changes.

Main Results:

Early CT signs include a target mass with preserved fascial planes.
Progressive changes involve bowel wall thickening, a characteristic layering effect, and potential mesenteric vascular traction.
Signs of obstruction (air-fluid levels) and advanced compromise (amorphous bowel shape, intraperitoneal fluid, intramural air) were observed.

Conclusions:

Computed tomographic (CT) imaging provides detailed insights into the spectrum of intussusception.
Specific CT findings can indicate the stage of intussusception and predict complications like bowel obstruction and vascular compromise.
