An intact male, 3-year old, Sapsari, weighing 29 kg with a history of respiratory distress, anorexia, abdominal distension, and depression for 1 day was referred. Radiographic findings included a C-shaped soft tissue mass in the mid-abdominal cavity and loss of serosal detail. Ultrasonographs showed splenomegaly with hypoechoic coarse parenchyma, loss of venous flow in the dilated splenic veins, and thrombi. Based on image findings, acute isolated splenic torsion was diagnosed. Splenectomy and prophylactic gastropexy was performed. Another case was a spayed female, 8-year old, Shih-tzu, weighing 3.7 kg with a history of intermittent abdominal pain and a palpable abdominal mass for 1 year. Radiographic findings showed splenomegaly characterized by a soft tissue round mass. Ultrasonographs revealed displaced splenic hilum and absence of venous flow in the dilated splenic vein. Chronic isolated splenic torsion was diagnosed and also splenectomy and gastropexy was performed. Two dogs were recovered normally after surgery without any complications. Acute form of isolated splenic torsion showed acute systemic clinical signs, severe C-shaped splenomegaly on radiographs, and loss of all of splenic venous flow, perivenous hyperechoic triangle sign, and thrombi on ultrasonographs. Chronic form of isolated splenic torsion showed chronic obscure clinical signs, moderate splenomegaly on radiographs, and partial loss of splenic venous flow on ultrasonographs.

Isolated splenic torsion is a rare disease, which is usually produced in deep-chest large breed dogs. A five-year old Pitbull terrier and a four-year old Yorkshire terrier were diagnosed as isolated splenic torsion with chronic form. Leukocytosis, anemia and elevated hepatic enzyme level were found in blood test and a large amount of ascites was observed. Abdominal radiography revealed splenomegaly and ascites and ultrasonography showed diffuse hypoechoic change of spleen in case 1 and hyperechoic change of spleen with focal hypoechoic regions in case 2, thromboembolism of splenic vein and abnormal direction of spleen. To identify the underlying disease of isolated splenic torsion, the histopathologic examination of excised spleen is essential and splenic neoplasia was found in case 2. Chronic isolated splenic torsion shows nonspecific clinical signs and laboratory results. Through diagnostic procedure, particularly ultrasonography, prompt diagnosis may be achieved and improve the prognosis of the patient.

A 5-year-old male German shepherd dog was presented with a 4 day-history of anorexia and depression. Abdominal radiographs showed a large soft tissue mass and loss of serosal detail. Ultrasonographs revealed splenomegaly with the lacy pattern parenchyma, perivenous hyperechoic region at the splenic hilum, and loss of splenic venous flow. Computed tomographic findings included the enlarged non-enhanced spleen except perivenous region at the splenic hilum and a whirled soft tissue mass at the splenic hilum. Exploratory laparotomy confirmed the diagnosis of splenic torsion. Ultrasonographic findings including lacy appearance, hyperechoic perivenous echogenicity and absence of splenic blood flow and CT findings including no or minimal enhancement of the spleen and a whirled appearance of splenic pedicle could be useful for diagnosing isolated splenic torsion in the dog.
