This 25 year old man presented through ER with left lower quadrant pain. Along with initial labs abdomen and pelvis ultrasound was requested, showed hyperechoic mass at site of patient's complaint and guarding at this area. It appeared non-compressible without internal vascularity. No associated abdomen or pelvis free fluid. CT scan was advised by our radiology department and confirmed fat density lesion at typical location anterior to sigmoid-descending colon junction findings are those of epiploic appendagitis. Follow-up scan was also advised.
