Primary Epiploic Appendagitis of the Appendix Vermiformis

Area of Science:

• Gastroenterology
• Radiology
• Surgical Pathology

Background:

• Primary epiploic appendagitis (PEA) is a rare, self-limiting condition.
• PEA often presents with symptoms mimicking acute abdominal emergencies like appendicitis or diverticulitis.
• Accurate diagnosis is crucial for conservative management and avoiding invasive procedures.

Observation:

• A 29-year-old female presented with acute right lower quadrant abdominal pain.
• Physical examination revealed localized tenderness; laboratory tests were unremarkable.
• Computed tomography (CT) identified a fat-density lesion adjacent to the appendix, leading to a PEA diagnosis.

Findings:

• CT imaging is key in diagnosing PEA, showing characteristic findings like a hyperdense rim around a fat-density lesion.
• The patient received conservative treatment with pain medication and recovered fully within a week.
• No surgical intervention or antibiotics were required.

Implications:

• PEA should be considered in the differential diagnosis of acute abdominal pain by emergency clinicians and radiologists.
• Utilizing ultrasound and CT can lead to accurate PEA diagnosis, preventing unnecessary interventions.
• Early and accurate diagnosis of PEA reduces healthcare costs and patient morbidity.
