APPENDICES epiploicae are normally present as fatty landmarks attached to the antimesenteric wall of the colon throughout its course. They are more numerous on the transverse and descending colon and are covered by the layer of visceral peritoneum which envelopes this structure. In general they receive little or no attention.
However, infarction of an isolated appendices epiploica can produce hemorrhagic and inflammatory changes which lead to peritoneal irritation. When such an event takes place, the subjective complaints and physical findings that develop may be of sufficient magnitude to require operation. Inflammatory changes in these fatty appendages may occur as a primary phenomenon due to impairment of blood supply or they may be a secondary manifestation of infection in an adjacent viscus. Since these structures often serve as repositories for colonic diverticula, infection in such a culde-sac may extend to the contiguous epiploica. The incidence of primary infarction is low, and
