Abstract

The purpose of this study was to analyze the CT signs of primary epiploic appendagitis. A retrospective search of the CT database over 12 months for this diagnosis revealed 11 cases. The clinical findings were recorded. Softcopy CT images were reviewed by two experienced abdominal radiologists (KS, DM) for location of lesion, size, shape, presence of central hyperdense focus, degree of bowel wall thickening, mass effect, and ancillary signs. Abdominal pain was the primary symptom in all patients. Preliminary diagnoses were appendicitis (n = 2), diverticulitis (n = 5), pancreatitis (n = 1), ovarian lesion (n = 1), or unknown (n = 2). Abdominal examination and white blood cell count were uninformative. CT examination revealed a solitary (n = 11), ovoid (n = 9) fatty lesion with some soft tissue stranding adjacent to the left colon (n = 6), transverse colon (n = 3), or right colon (n = 2). Central hyperdensity (n = 5), mild bowel wall thickening (n = 2), and parietal peritoneal thickening (n = 4) were also seen. In 4 patients the lesions were not visible on follow-up CT examination performed 23-184 days later. Primary epiploic appendagitis can clinically mimic other, more serious inflammatory conditions. Knowledge of its findings on CT would help the radiologist make the diagnosis and allow a more conservative approach to patient care.
