Omental torsion associated with splenic torsion in a dog

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.
