Omentum torsion is a rare cause of acute abdomen. Omentum torsion generally takes place on the right side and clinically mimics appendicitis, so for this reason omentum torsion is generally diagnosed by laparatomy carried out for appendicitis. For differential diagnosis from appendicitis it is important that pain starts suddenly after a heavy meal or hard exercise in omentum torsion and also pain is not accompanied with nausea, vomiting and anorexia. A 54 year-old female patient with suspected appendicitis was operated on and a right paramedian incision was employed. Primary omentum torsion was diagnosed and the infarcted tissue resected. We suggest that in cases where acute appendicitis is uncertain omentum torsion and other pathologies must be considered. In these cases a paramedian incision and diagnostic laparascopy may provide benefit for diagnosis. Keywords: Omentum torsion, acute appendicitisReceived: 12.01.2011Accepted: 09.02.2011 ÖZETOmentum torsiyonu oldukça nadir görülen bir akut karın nedenidir. Omentum torsiyonu sıklıkla sağda olması ve kliniğinin akut apandisite benzer olması nedeni ile sıklıkla akut apandisit nedeni ile yapılan laparatomide tanı almaktadır. Ancak ağrının sıklıkla aşırı yemek, ani hareket veya ağır egzersizi takiben birden başlaması ve bulantı, kusma, iştahsızlığın genelde eşlik etmemesi apandisitten ayırıcı tanıda önem arz eder. Bizde akut apandisit kliniği şüpheli olan 54 yaşında bayan olgu sağ paramedian kesi ile opere edildi ve primer omentum torsiyonu tanısı konarak torsiyone segment rezeke edildi. Akut apandisit kliniği şüpheli olan olgularda omentum torsiyonu ve benzeri patolojiler olabileceği düşünülerek paramedian kesi, diagnostik laparoskopi gibi alternatiflerin göz önünde bulundurulmasının faydalı olacağını düşün-mekteyiz.

“…The CT findings of omental infarction progress from an illdefined, heterogeneous fat density lesion in the early stage (< 15 days) to a well-defined, smaller lesion with a hyperdense rim (> 30 days) (47). The appearance of postoperative omental infarction on CT can be classified into four types: type 1 (ill-defined, heterogeneous, fat density lesion); type 2 (well-defined fat density lesion with rim enhancement); type 3 (well-defined heterogeneous lesion with a fat component); and type 4 (well-defined heterogeneous lesion without a fat component) (52).…”

“…Precipitating factors of primary or secondary torsion are similar: sudden increase in intraabdominal pressure after heavy meals, heavy exertion, and change in body position, coughing or sneezing. These conditions may result in sudden displacement of the omentum which leads omental torsion (2,6) . The clinical presentation of primary and secondary omental torsion is similar and occurs in the fourth and fifth decades, and more seen in males than females (7) .…”

“…The recommended treatment is resection of the involved segment of the omentum. On the other hand literature presents few cases on omental torsion that have successfully been managed conservatively, especially in patients without complications (1,2,6). cOncluSıOn Omental torsion is a rare cause of acute abdominal pain but should be included in the differential diagnoses of acute abdomen, especially for patients with unclear symptoms and nonspecific abdominal pain.…”

Background: Omental torsion is an uncommon cause of an acute abdomen. Most often it presents with sign and symptoms of acute appendicitis. We report this case to reveal the clinical presentation and computed tomography imagine findings of omental torsion as an uncommon cause of abdominal pain. case report: A 45-year-old male presented to the emergency department complaining of right lower abdominal pain. There was no pathological sign except millimetric stones in the gall bladder and free fluid in the right lower quadrant in abdominal ultrasonography. Then computed tomography was performed and it shoved omental whirl sign and increased density in great omentum consistent with omental torsion. Thus, a diagnosis of omental torsion was made immediately, which was confirmed by subsequent surgery. conclusion: Omental torsion is a rare cause of acute abdominal pain, but especially it will be remembered for patients with unclear symptoms and nonspecific abdominal pain.
