“…CT characteristics included heterogeneous fatty mass that is located between the anterior abdominal wall and the bowel with a whirled pattern of concentric hyperattenuated linear strands. These findings were similar to that reported by other authors (15)(16)(17). In the current study, omental thickening could be detected in all of our studied patients.…”

Objective: To assess the diagnostic value of multidetector computed tomography (MDCT) in differentiation of benign and malignant omental lesions. Patients and methods: MDCT scan was performed for 37 patients with omental lesions after administration of oral and intravenous contrast. The CT diagnosis was compared with the final histopathological findings. Sensitivity, specificity, and diagnostic accuracy of MDCT were calculated using surgical and histopathological findings as the gold standard. Results: MDCT findings of all cases with omental torsion, cystic lymphangioma, and loculated fluid in the greater omentum correlated with the surgical and histopathological findings with 100% diagnostic accuracy. However, the diagnosis was missed in two patients from seven (2/7) with tuberculous peritonitis and in two patients from 21 (2/21) with peritoneal carcinomatosis with sensitivity, specificity and diagnostic accuracy of 73%, 92%, 85% and 90%, 95%, 93%, respectively. Conclusion: MDCT is an excellent diagnostic tool for evaluating omental lesions, especially those present with nonspecific clinical manifestations.

“…15 On abdominal ultrasound, an ovoid, hyperechoic mass with hypoechoic tubular or patched structures near to the peritoneum or other organs might be suggestive of this disease. 16 Colour Doppler ultrasound can be useful to determine the absence of vascularity. In this case, the abdominal ultrasound revealed findings similar to those reported in human beings with omental torsion; however, given the rarity of this condition in animals, a pancreatic abscess was initially suspected.…”

“…The use of intravenous contrast has been reported to enhance visualisation of the twisted vascular pedicle. 16 Definitive diagnosis of omental torsion is usually achieved by exploratory laparoscopy or laparotomy. 16 17 Surgical resection of the affected omentum is the treatment of choice in cases of omental torsion.…”

A five-year-old female intact German shepherd presented with an acute onset of abdominal pain. Abdominal ultrasound revealed a 5-cm encapsulated, heterogeneous structure with hypoechoic patches near the right pancreatic lobe. An exploratory laparotomy revealed a partially encapsulated necrotic mass located at the greater omentum. A partial omentectomy was performed. Histopathological findings were consistent with necrosis of the omentum secondary to omental torsion. Postoperative course was uneventful. Omental torsion is a rare cause of abdominal pain in human beings and animals. In veterinary medicine, it has only been reported four times, none of them in a dog. Omental torsion should be included as a differential diagnosis for dogs with acute abdominal pain and gastrointestinal signs. Imaging studies can aid in the diagnosis but exploratory laparotomy is probably the best diagnostic and therapeutic intervention in these cases. Prognosis after surgery appears to be good but an underlying aetiology should be searched thoroughly.

“…In humans, secondary OT can result from congenital adhesions of the omentum to the caecum, ascending colon or both. It can result also from acquired omental adhesions to abdominal cysts, tumours, hernias, intra‐abdominal inflammatory focus or postsurgical wounds, predisposing the remainder of the omentum to twist around an adhesion acting as a pivot 3 9–11 20–23…”

“…Diagnosis of OT in humans and animals may be difficult since it resembles many conditions causing acute abdominal pain or abdominal enlargement 3 8 11 12 20. Abdominal radiographs are usually unrewarding, probably because of the small size of the omentum and because intestinal peristalsis typically is not affected 24.…”

A 5-year-old female spayed Cane Corso was referred for further investigation and treatment of a splenic torsion and an abdominal mass. The dog presented with a history of anorexia, depression and vomiting of 4 days’ duration. Physical examination revealed pain on abdominal palpation. On a plain radiograph of the abdomen, a cranial abdominal mass and splenomegaly were present. On CT images of the abdomen, a twisted splenic pedicle, splenic torsion and a well-defined mass in the left cranial abdomen were observed adjacent and caudal to the greater curvature of the stomach. The dog underwent a midline coeliotomy, a total splenectomy and a partial gastrectomy to resect the mass attached to the great curvature of the stomach. Omental torsion was diagnosed on gross and histological examinations of the mass. The dog was reported by the owners to be free of clinical signs 2 years after surgery.
