“…They also help to exclude other pathologies like omental deposits and tumours [ 6 , 8 ]. CT scan shows characteristic appearances of twisted omentum like caking, hazy stranding, nodules, signs of whirl fatty mass formation with concentric linear strands and diffuse infiltration [ 2 , 7 , 8 , 12 , 13 ] These features may mimic recurrent abdominal malignancy [ 9 ]. When diagnosis by radiological imaging fails, laparoscopy is then the next option for definitive diagnosis and perhaps for treatment [ 5 ].…”

Background Omental Infarction (OI) is uncommon and mimics common causes of acute abdomen. It is important to differentiate it from other abdominal conditions that require emergency management. It was first reported in literature in 1896 and about 400 cases have been reported till date. Case presentation We reported on a 41 year-old Para 0+0 Ibo house wife who presented with 10 years history of supra-pubic mass and five months history of excessive menstrual flow. After physical examination, a diagnosis of symptomatic uterine fibroid was made. She had myomectomy and the raw surface created after the excision of the myomas was covered with omentum. Wound infection developed on the 8th post-operative day leading to a wound breakdown and later partial extrusion of infarcted omental tissue through the dehisced wound. During re-exploration, the infarcted omental tissue was extracted and the residual abdominal abscess was drained. Surgical site wound infection occurred on the 3rd day after re-operation and a sub-acute intestinal obstruction developed on the 4th day thereafter which responded to conservative management. Conclusion Careful surgical technique is imperative when utilizing the omentum for reconstructive abdominal surgery. Torsion of the omentum and creation of excess tension while using the omentum for reconstructive procedures should be avoided and increase awareness of this uncommon disease condition by the surgeon is also important. This case is to report a rare finding of omental infarction following myomectomy.

“…This may be due to the peritoneal defense mechanisms for wound isolation which prevents the spread of the abdominal infection by wrapping around the lesion. In addition, the omentum and mesentery act as boundaries for pathological processes for disease localization [ 22 25 26 27 ]. In patients of severe inflammatory disease such as necrotic pancreatitis, local inflammation can spread over the surrounding tissue or even progress to a systemic response and cause fat stranding in remote places apart from the lesion [ 4 5 28 ].…”

Background Fat stranding is a non-specific finding of an increased fat attenuation on computed tomography (CT) images. Fat stranding is used for detecting the underlying lesion in humans. Objectives To assess the clinical significance of fat stranding on CT images for identifying the underlying cause in dogs and cats. Methods In this retrospective study, the incidence, location, extent, distribution, and pattern of fat stranding were assessed on CT studies obtained from 134 cases. Results Fat stranding was found in 38% (51/134) of all cases and in 35% (37/107) of tumors, which was significantly higher in malignant tumors (44%) than benign tumors (12%). Moreover, fat stranding was found in more than two areas in malignant tumors (16/33) and in a single area in benign tumors (4/4). In inflammation, fat stranding was demonstrated in 54% (7/13) in a single area (7/7) as a focal distribution (6/7). In trauma, fat stranding was revealed in 50% (7/14) and most were in multiple areas (6/7). Regardless of the etiologies, fat stranding was always around the underlying lesion and a reticular pattern was the most common presentation. Logistic regression analysis revealed that multiple areas ( p = 0.040) of fat stranding and a reticulonodular pattern ( p = 0.022) are the significant predictors of malignant tumor. Conclusions These findings indicated that CT fat stranding can be used as a clue for identifying the underlying lesion and can be useful for narrowing the differential list based on the extent and pattern.
