Caption: CT Scan
Description: CT scan shows fat-density lesion with surrounding hyperdense rim and inflammation abutting the sigmoid colon and anterior abdominal wall musculature.
Differential Diagnosis acute diverticulitis
acute epiploic appendagitis

Final Diagnosis acute epiploic appendagitis
Discussion Acute epiploic appendagitis is an uncommon cause of abdominal pain,  that occurs secondary to torsion or spontaneous venous thrombosis of a draining vein from the serosal surface of the colon.

Clinically, it is most often mistaken for acute diverticulitis.

Acute epiploic appendagitis is associated with obesity and  hernia .

Rarely, acute epiploic appendagitis may result in adhesion, bowel obstruction, intussusception, intraperitoneal loose body, peritonitis .

Epiploic appendagitis is a self-limiting disease that has been reported in approximately 1% of patients clinically suspected of having appendicitis .
