Recurrent Omentum Strangulation as a Rare Case of Acute Abdomen Omentum tumors could be caused by malignant or benign tumors and also by vascular etiology through pseudotumorous omentitis or torsion. At admission most of the patients were suspected of having acute cholecystitis or appendicitis. We report about a 50-year-old patient with a recurrent omentum strangulation which was shown to be a tumor in the right lower abdomen. The preoperative diagnosis of omentum tumors and their etiology is difficult. C-reactive protein is in most cases elevated. Ultrasound and abdominal CT are helpful in choosing and planning the therapeutic strategy, with the laparoscopic approach being the treatment of choice. Conservative therapy is reserved for special cases.
