Perigastric appendagitis: CT and clinical features in eight patients
Clinical Radiology
|October 4, 2014
Summary
Perigastric appendagitis (PA) presents as epigastric pain on CT scans. Recognizing this distinct entity avoids unnecessary tests and interventions, as symptoms often resolve spontaneously.
Area of Science:
- Radiology
- Gastroenterology
- Abdominal Imaging
Background:
- Perigastric appendagitis (PA) is an emerging clinical entity.
- Accurate CT diagnosis is crucial to prevent unnecessary investigations.
Purpose of the Study:
- To describe the CT findings of perigastric appendagitis (PA).
- To establish PA as a distinct clinical entity.
Main Methods:
- Retrospective review of eight PA patients' clinical data and CT findings.
- Consensus review of CT images by two experienced abdominal radiologists.
- Literature review and summarization.
Main Results:
- Eight patients presented with epigastric pain; none had fever or leukocytosis.
- CT revealed ovoid fat inflammation in perigastric ligaments; two had gastric wall thickening.
- Five patients initially misdiagnosed underwent further unnecessary testing.
Conclusions:
- Perigastric appendagitis (PA) can mimic acute abdominal conditions.
- Correct CT diagnosis of PA enables conservative management and avoids interventions.
- Radiologists must recognize CT signs of PA for accurate diagnosis.

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...

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...

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...

The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
