Summary
Background: Primary epiploic appendagitis is a relatively rare condition in which torsion and inflammation of an epiploic appendix result in localized abdominal pain. This is a non-surgical situation that clinically mimics other conditions requiring surgery such as acute diverticulitis or appendicitis.
Objective: To investigate the clinical, laboratory and radiological findings of the disease.
Methods
:
During the years 1995-88 five patients with primary epiploic appendigitis were diagnosed at our institution. The clinical, laboratory and imaging results were summarized and compared to previously reported series. Emphasis was placed on the computed tomography findings, which are the gold standard for diagnosis.
Results: All our patients (two males and three females, mean age 47 years) presented with left lower quadrant abdominal pain. CT proved to be the imaging modality of choice in all patients by showing a pericolic fatty mass with an increased attenuation as compared to normal abdominal fat. In all cases the mass was surrounded by a high attenuation rim, and focal stranding of the fat was observed. In no case was there thickening of the adjacent bowel wall. This serves as an important, and previously unreported, clue for diagnosis.
Conclusion: Primary epiploic appendagitis is a relatively rare condition that may be clinically misdiagnosed, resulting in unnecessary surgical intervention. Judicious interpretation of CT may lead to early diagnosis and ensure proper conservative treatment.
