This subject has recently been reviewed by Mullen,1 but the case reported here presents findings that are not in accord with most of the previously reported cases. Reidel,2 quoted by Fuller,3 says, "Given an instance in which the normal omentum is free from pathology of whatever kind, torsion or rotation would probably never occur." Mullen classifies torsion of the omentum into three kinds.
1. Torsion in cases in which the omentum has in its distal end a mass that is free or has become free through twisting. Luckett4 says, "Nearly every case of reported torsion of the omentum was associated with some form of inflammation, either within or without the abdomen, as in a hernia." Mullen thinks hernias play an important rôle in the causation of omental torsion, as is evident from the large percentage of reported cases in which there has been an associated hernia.
