Case report: pericolic abscess secondary to torsion of an appendix epiploica.

Torsion of the appendices epiploicae is a rare condition which may present with acute abdominal pain and mimic appendicitis. Untreated, peritonitis or intestinal obstruction may result. We present a case in which torsion of an appendix epiploica led to the development of a pericolic abscess communicating between the colon and lesser sac. To our knowledge these radiological findings have not been described previously.
