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.

5년령의 수컷 독일 셰퍼드견이 4일 동안의 식욕부진, 침울 등의 증상으로 내원하였다. 복부의 일반 방사선 사진에서 연부조직 밀도의 대형 종괴가 관찰되었다. 또한 종괴 변연과 주변에 장막세부음영의 소실이 관찰되었다. 복부 초음파 검사를 통해 고에코를 나타내는 비장문의 비장정맥 주위를 제외하고 전반적으로 저에코를 나타내는 비장 종대를 관찰하였고, 펄스파 도플러검사에서 비장정맥에 혈류신호가 없음을 확인하였다. 복부 CT 검사에서 비장문에 위치한 비장정맥 주위에서의 조영증강효과를 제외한 비장의 나머지 부위에서의 조영증강효과는 관찰되지 않았다. 비장의 혈관줄기의 염전을 나타내는 소용돌이 모양의 연부조직 밀도의 종괴를 확인하였다. 탐색적 개복술을 통해 단독으로 발생한 비장 염전을 진단하였다. 초음파 검사에서 레이스 형태의 실질 변화와 도플러 검사시 비장 정맥의 혈류 신호 소실, CT 영상에서 비장 뿌리 부위의 소용돌이 모양의 소견 등이 비장 염전의 유용한 영상학적 특징으로 생각된다.
