Infarction of the omentum as a primary disease or secondary to idiopathic torsion is considered a rare entity. Idiopathic torsion of the omentum consists of an omental twist in the absence of any recognizable etiologic factor such as a hernia, inflammatory process, or adhesions. The syndrome is clinically indistinguishable from acute appendicitis when the infarcted segment lies in the right lower abdominal quadrant. Between March 1, 1953, and March 1, 1954, 145 laparotomies were performed at the 3750th U. S. A. F. Hospital for acute appendicitis: in two cases, infarction of the omentum secondary to primary torsion was found.
