Omental torsion is a very rare cause of acute abdomen. Clinically, it mimics other common pathologies such as acute appendicitis, acute diverticulitis and acute cholecystitis. It is therefore no surprise, that it was rarely diagnosed pre operatively before the advent and easy availability of modern imaging techniques. CT scan, in particular, can diagnose omental torsion with confidence pre operatively. This can make conservative treatment possible in cases of primary omental torsion and guide regarding the appropriate treatment in cases of secondary torsion. We present a case of a young male patient who presented to Emergency department with symptoms of acute abdomen. Clinical and laboratory findings were non-specific for any specific cause of acute abdomen. CT scan, however, showed omental fat stranding with whirlpool sign representing omental torsion which was seen to be secondary to left inguinal hernia. Patient was operated in emergency and necrotic omentum was resected and hernia repaired. Post-operative recovery was uneventful.
网膜扭转是一种非常罕见的急性腹痛原因。临床上，它模仿其他常见的病理情况，如急性阑尾炎、急性憩室炎和急性胆囊炎。因此，在现代成像技术出现和易于获得之前，术前很少能诊断出这种疾病，这并不奇怪。特别是 CT 扫描可以在术前有信心地诊断网膜扭转。这可以使原发性网膜扭转的保守治疗成为可能，并指导继发性扭转的适当治疗。我们报告了一例年轻男性患者，他因急性腹痛症状就诊于急诊科。临床和实验室检查结果对任何特定原因的急性腹痛均无特异性。然而，CT 扫描显示网膜脂肪绞索，呈漩涡征，代表网膜扭转，继发于左侧腹股沟疝。患者在急诊手术中，切除了坏死的网膜并修复了疝。术后恢复顺利。
