A 61-year-old man presenting with abdominal pain and fever refractory to antibiotics underwent diagnostic laparoscopy and non-mass-forming isolated omental panniculitis was identified. He presented with left-upper-quadrant abdominal pain. Laboratory data and the CT findings suggested intraabdominal bacterial disease in the splenic flexure, which we treated with antibiotics and fasting. He clinically improved once, but later relapsed with abdominal pain migration to the left-lower-quadrant. CT re-examination revealed no inflammation in the splenic flexure, but attenuation of adipose tissue in the greater omentum. We partially extracted the greater omentum during diagnostic laparoscopy and diagnosed omental panniculitis and administered steroids. He improved and was discharged three days after starting oral prednisone and is recurrence-free with a close follow-up. The characteristic CT feature of omentum panniculitis is a high-density fatty mass, but we noted only an attenuation of adipose tissue in the greater omentum. Diagnositic laparoscopy is useful for diagnosing this condition.
