Summary
Left-sided omental torsion, a rare condition, can cause severe flank pain. Characteristic CT findings include a whirling vascular structure in the omentum, aiding in diagnosis and guiding treatment decisions.
Area of Science:
- Abdominal Imaging
- Surgical Pathology
Background:
- Omental torsion is an uncommon surgical emergency, often presenting with non-specific abdominal pain.
- Left-sided omental torsion is particularly rare, making pre-operative diagnosis challenging.
Observation:
- A 34-year-old male presented with acute left flank pain.
- Computed tomography (CT) revealed a hyperdense vascular structure with whirling streaks in the greater omentum, extending into an inguinal hernia sac.
Findings:
- Surgical exploration confirmed left-sided torsion of the greater omentum.
- The CT findings of a fatty mass with a whirling pattern are characteristic of omental torsion.
Implications:
- Accurate pre-operative diagnosis of omental torsion is crucial.
- Early diagnosis may allow for conservative management, potentially avoiding surgery.
