Ultrasonographic findings of a rare case of splenic rupture and torsion in a dog

Abstract

AbstractA 7‐year‐old dog presented with acute lethargy, anorexia and vomiting. Ultrasonographic examination revealed a hypoechoic mass lesion in the left abdomen, characterised by a hilum‐like structure and intraparenchymal gas. A mild amount of hyperechoic peritoneal effusion was present. An apparently normal spleen was visualised, which was not associated with the described mass lesion. Surgery revealed a presumed previously ruptured and separated spleen. The caudal portion of the spleen was acutely torsed and there was a mild amount of peritoneal fluid present. Histopathology confirmed splenic torsion of the previously ruptured and separated caudal splenic segment. Bacterial culture of the peritoneal effusion after enrichment indicated Staphylococcus aureus. The patient recovered successfully and maintained excellent clinical conditions at 14‐month follow‐up. Splenic torsion of a ruptured splenic segment should be considered as a differential diagnosis for an emphysematous mass containing a hilum‐like structure in the abdomen in dogs.
