Summary
Appendicitis and diverticulitis are common causes of acute abdomen in adults. Accurate diagnosis using imaging like CT scans is crucial to avoid errors from incorrect procedures or unusual presentations.
Area of Science:
- Gastroenterology
- Radiology
- Abdominal Imaging
Background:
- Febrile acute abdomen in adults is frequently caused by appendicitis and colonic diverticulitis.
- Imaging modalities such as ultrasound and computed tomography (CT) are primary diagnostic tools.
Purpose of the Study:
- To highlight potential diagnostic pitfalls in imaging acute abdomen.
- To emphasize the importance of appropriate imaging selection and protocol adherence.
Main Methods:
- Review of common causes of acute abdomen.
- Analysis of imaging (ultrasound, CT) findings in appendicitis and diverticulitis.
- Identification of factors contributing to misdiagnosis.
Main Results:
- While imaging diagnosis is typically straightforward, errors can arise from unsuitable procedures or incorrect protocols.
- Anatomical variations, inflammatory cancers, and complicated disease forms can mimic other conditions.
- Associated peritoneal inflammatory signs may also lead to diagnostic confusion.
Conclusions:
- Careful selection of imaging procedures and adherence to correct protocols are essential for accurate diagnosis.
- Awareness of anatomical variants and complicated presentations is vital to prevent misdiagnosis of appendicitis and diverticulitis.

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...
01:22Appendicitis-I: Introduction
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

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...
01:26Inflammatory Bowel Disease I: Introduction
Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows “skip lesions” in which...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The disease course is marked...
