[Frequency and epidemiology of primary epiploic appendagitis on CT in adults with abdominal pain].

Abstract

PURPOSE Advances in medical imaging have improved the presurgical diagnosis of isolated epiploic appendagitis. The authors assess its relative frequency and define its main epidemiological criteria. PATIENTS AND METHODS Study of an adult population presenting with abdominal pain and evaluated by CT over a 3 year period. Evaluation for the presence of an isolated fat density paracolic mass with hyperdense periphery. A review of the literature was performed as well. RESULTS The frequency of epiploic appendagitis is estimated at 1.3% and its incidence at 8.8 cases/million/year. The typical patient profile is a young to middle aged male presenting with left flank and lower quadrant pain. Obesity, GI symptoms, fever, and leukocytosis are characteristically absent while elevation of the CRP is typical. CT shows the lesion along the anterolateral margin of the descending or sigmoid colon. Spontaneous resolution usually occurs within 8 days. CONCLUSION Our results confirm epidemiological data from the literature. Knowledge of the imaging features of epiploic appendagitis will ensure conservative patients management and avoid unnecessary surgery.
