Gray-scale and color Doppler sonographic diagnosis of epiploic appendagitis

Depending on its location, epiploic appendagitis may mimic nearly any acute abdominal condition. We present the case of a patient with left lower quadrant pain. Sonography demonstrated an ovoid, hyperechoic, noncompressible lesion at the point of tenderness but no inflammatory changes in the adjacent colonic wall. Color Doppler sonography showed no flow in the lesion. Based on the sonographic diagnosis of epiploic appendagitis, conservative treatment was given, with complete recovery in 5 days. Awareness of these sonographic findings may aid in the early diagnosis of epiploic appendagitis and avoid unnecessary treatment.
