Summary
Computed tomography (CT) findings can help diagnose isolated caecal ischaemia (ICA). Key indicators include thickened caecal walls and, in some cases, caecal pneumatosis, aiding differentiation from other conditions.
Area of Science:
- Radiology
- Gastroenterology
- Abdominal Imaging
Background:
- Isolated caecal ischaemia (ICA) presents diagnostic challenges.
- Accurate CT imaging is crucial for timely diagnosis and management.
Purpose of the Study:
- To outline CT diagnostic characteristics of ICA.
- To differentiate ICA from conditions with similar clinical presentations.
Main Methods:
- Retrospective review of CT findings in 4 ICA patients.
- Analysis of caecal wall thickness, peri-caecal fat, free fluid, pneumatosis, appendix, and vasculopathy signs.
Main Results:
- All cases showed thickened caecal walls with abrupt transition to the ascending colon.
- Characteristic central image noted in caecal thickening.
- Caecal pneumatosis observed in two patients; appendices were normal.
Conclusions:
- Caecal wall thickening with oedematous features, normal appendix, ileum, and colon suggest ICA.
- Presence of pneumatosis strengthens the diagnosis of caecal ischaemia.

01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
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...

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
01:25Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
