Appendices epiploicae (also called epiploic appendages) are small, fat-filled pouches that hang from the colon. Though often overlooked, these structures can become inflamed or twisted, mimicking serious abdominal conditions like appendicitis or diverticulitis.
This post offers a clear diagram and detailed explanation to help students understand the anatomical and clinical relevance of these fatty tags.
 |
| Small, finger-like fat-filled outpouchings of peritoneum along the teniae coli of the large intestine. |
Anatomical Location
- Found only on the colon (not on the rectum or small intestine)
- Most numerous on the sigmoid colon and transverse colon
- Attached along the teniae coli, especially near the free tenia (tenia libera)
Function
- No well-defined physiological function
Believed to:
Provide fat storage, Offer cushioning or mechanical protection, Possibly play a minor immunological role
Clinical Relevance
Epiploic Appendagitis:
- Inflammation due to torsion or venous thrombosis
- Presents with acute abdominal pain (can mimic appendicitis or diverticulitis)
- Diagnosed via CT scan
- Self-limiting and managed conservatively
Visualize the colon and locate the teniae coli — appendices epiploicae hang along these bands. Diagrams with color-coded fat pouches help anchor this memory.
