Summary
Duodenal diverticula (Dd) are common but often asymptomatic, found incidentally in 0.46% of abdominal CT scans. These lesions increase with age and can mimic other conditions or cause complications like bleeding.
Area of Science:
- Gastroenterology
- Radiology
- Abdominal Imaging
Background:
- Duodenal diverticular disease is frequently encountered but challenging to diagnose clinically.
- Symptomatic presentation is uncommon, with vague symptoms and a low rate (1-2%) requiring surgical intervention.
Purpose of the Study:
- To determine the prevalence of duodenal diverticulum (Dd) in patients undergoing abdominal computed tomography (CT).
Main Methods:
- A retrospective analysis of abdominal CT scans was conducted.
- Cases with incidentally identified duodenal diverticula were reviewed.
- Clinical data including location, type, and complications were recorded.
Main Results:
- Out of 12,704 CT scans, 50 patients (0.46% prevalence) had duodenal diverticula.
- The majority (60%) were female, with a mean age of 69 years.
- Diverticula were most common in the second (26%) and third (48%) portions of the duodenum; 2% complicated by hemorrhage requiring surgery.
Conclusions:
- Duodenal diverticula were identified in 0.46% of abdominal CT scans, with 94% detected incidentally.
- Prevalence increases with age.
- Duodenal diverticula can mimic pancreatic head cystic neoplasms (28%) and lead to complications such as bleeding (2%).

01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
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...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
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...

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:29Appendicitis-II: Diagnostic Studies and Management
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
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...
