Acute epiploic appendagitis: ultrasound and computed tomography findings of a rare case of acute abdominal pain and the role of other imaging techniques

Purpose

Acute epiploic appendagitis (EA) is a relatively rare, benign and local inflammatory disease involving the epiploic appendices. Unlike its mimics, EA is generally a self-limiting inflammatory disease and can be treated conservatively.

Case presentation

A 33-year-old Caucasian man presented to our emergency department with a sever and sharp left iliac fossa pain. He underwent abdominal X-ray, ultrasound (US) and computed tomography (CT) evaluations.

Conclusion

We illustrate US and CT findings to increase the radiologists’ awareness of this condition and to avoid diagnostic delay and unnecessary use of antibiotics, hospitalization and surgery.

A pediatric case report of Epiploic appendagitis presented with abdominal pain

INTRODUCTION

Epilopic appendagitis (EA) is an uncommon condition of abdominal pain caused by the local inflammation of the fat-filled peritoneal outpouchings due to torsion or thrombosis of its vessels leads to ischemia and gangrenous necrosis of the aappendages, as it can cause peritoneal irritation, acute ischemia, and fat necrosis.

CASE REPORT

We present a case of epilopic appendagitis mimicking appendicitis of a 10 years old male, presented to the emergency department with severe right quadrant pain pointedly at the right lumbar area. Associated with constipation and nausea for once. Computed tomography (CT) scan with contrast was performed showing an ovoid fat structure with thin enhancing rim and surrounding inflammatory stranding as well as prominent lymph nodes at hepatic flexure, free fluid and no evidence of appendicitis. The patient was discharged with pain control medications.

DISCUSSION

Epiploic Appendages are mobile, pedunculated peritoneal out pouches. Considering its mobility and narrow pedicle appendages are disposed to torsion leading to appendagitis causing local inflammation, peritoneal irritation, acute ischemia, and fat necrosis. The patient's main complaint would be a subacute lower abdominal pain, left-sided in 60-80% of cases.

CONCLUSION

Early recognition of this condition is crucial to avoid an operation when unnecessary leading to prolonged hospital stays. The management is conservative with analgesic.
