Abstract:
Primary epiploic appendagitis (PEA) occurs secondary to inflammation of an epiploic appendage, and is considered to be a rare cause of acute abdomen. In this case report, we describe the magnetic resonance imaging (MRI) findings of PEA correlated with computed tomographic (CT) findings. MRI findings included an oval shaped fat intensity mass with a central dot on T1- and T2-weighted images, which possessed an enhancing rim on postgadolinium T1-weighted fat saturated images. The lesion was best visualized on postcontrast T1-weighted fat saturated images. MRI findings of PEA should be considered in the differential diagnosis with the other causes of acute abdominal pain.
Insights
Primary epiploic appendagitis (PEA) is a rare cause of acute abdomen. This case report details MRI findings of PEA, correlating them with CT scans for diagnosis.
Area of Science:
- Radiology
- Gastroenterology
- Abdominal Imaging
Background:
- Primary epiploic appendagitis (PEA) is an uncommon cause of acute abdominal pain, often presenting a diagnostic challenge.
- Accurate diagnosis of PEA is crucial to avoid unnecessary surgical interventions.
Observation:
- This case report focuses on the magnetic resonance imaging (MRI) findings of PEA.
- The study correlates MRI findings with computed tomographic (CT) findings for comprehensive evaluation.
Findings:
- MRI revealed an oval, fat-intensity mass with a central dot on T1- and T2-weighted images.
- An enhancing rim was observed on postgadolinium T1-weighted fat-saturated images, with optimal visualization on postcontrast sequences.
Implications:
- MRI findings of PEA are crucial for differential diagnosis of acute abdominal pain.
- Integrating MRI into the diagnostic workup can improve the accuracy of PEA diagnosis.
- Understanding these specific MRI characteristics aids clinicians in differentiating PEA from other acute abdominal conditions.
