Omental torsion diagnosed by abdominal contrast-enhanced computed tomography: A case report

Table 2 Literature-review table

Characteristic	Clinical features and diagnostic-treatment key points of omental torsion
Etiology	Primary due to obesity, anatomical variants (e.g., tongue-like or bifid omentum), and sudden increases in intra-abdominal pressure. Secondary due to hernias, tumors, cysts, and surgical adhesions
Presenting symptoms	Abdominal pain, low-grade fever or normal body temperature, nausea and vomiting, and localized abdominal tenderness
Age range	Fourth to sixth decade
Imaging examination	Ultrasound: Hyperechoic, noncompressible ovoid mass near the peritoneum with no blood flow signal
	CT: Swirl sign
Treatment	Some can be treated conservatively. Laparoscopy is the preferred surgical approach
Outcome	Good specially if surgically treated
Potential modifying factors	The degree, duration, and vascular compromise of the torsion

CT: Computed tomography.
