Nonocclusive ischemic colitis in a 12-year-old girl: value of unenhanced spiral computed tomography

Abstract:
A 12-year-old girl was hit by a car and arrived in the emergency room in hemorrhagic shock. Contrast-enhanced computed tomography of the abdomen showed traumatic rupture of the liver and large amounts of intraperitoneal hemorrhage. Unenhanced computed tomography showed a hyperdense thickening of the wall of the descending colon. This finding was consistent with a nonocclusive ischemic colitis, which was confirmed some days later by endoscopy, at a time when the patient had already developed Gram-negative bacteremia. We discuss the pathogenesis of nonocclusive ischemic colitis, computed tomography findings, and the value of unenhanced computed tomography.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
