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.

Purpose : To evaluate the reliability and clinical usefulness of ultrasonography in the temporomandibular joint (TMJ). Materials and Methods : Parasagittal and paracoronal 1.5 T MR images and 7.5 MHz ultrasonographs of 40 TMJs in 20 asymptomatic volunteers were obtained. Disc position using MR imaging was evaluated and the distance between the lateral surface of mandibular condyle and the articular capsule using MR image and ultrasonograph of 27 TMJs with normal disc position was measured and compared. Intraobserver and interobserver measurements reliability was evaluated by using interclass correlation coefficients (ICC) and measurement error. Also, the distance measured on ultrasonographs was compared, according to mouth position and disc postion. Results : The normal disc position was found in 27 of 40 asymptomatic joints. At the intraobserver reliability of measurement, ICC at the closed and open mouth position were 0.89 and 0.91. The measurement error was 0.4% and 0.5%. At the interobserver reliability, ICC at the closed and open mouth position were 0.92 and 0.81. The measurement error was 0.4% and 0.7%. At the TMJ with normal disc position, the distances between the lateral surface of mandibular condyle and the articular capsule measured on MR images and ultrasonographs were $2.0{\pm}0.7mm,\;1.8{\pm}0.5mm$, respectively (p<0.05). On the ultrasonographs, the distances at open mouth position were $1.2{\pm}0.5mm$ (p<0.05). At the TMJ with medially displaced disc, the distances at the closed and open mouth position were $1.3{\pm}0.3\;mm\;and\;0.9{\pm}0.2\;mm$ (p<0.05). Conclusion : The results suggest ultrasonography of TMJ is a reliable imaging technique for assessment of normal disc position.

A 3-year-old yorkshire terrier was examined because of the green-like vaginal discharge. Abdominal ultrasonographs revealed dead fetuses in the abdominal cavity. Surgical exploration revealed fetuses located in the region of the uterine wall, the omentum, the ileum, and the upper right side of the liver respectively. Fetal structures were removed and an ovariohysterectomy was performed. The abdominal cavity was flushed with warm saline and then the incision closed. These fetuses were at different stages of development. It was suggested that the development of the fetuses apparently continued in extrauterine pregnancy until the blood supply became inadquate for further growth.

Two dogs were referred with the clinical signs of depression and constipation, respectively. One dog with depression had hypoglycemia on biochemistry. On survey abdominal radiographs, a soft tissue density round mass with calcified spots was identified cranial to the urinary bladder. On ultrasonographs, a solitary oval heterogeneous complex-echoic mass with well-defined margin was found. On surgery, the mass was pedunculated and originated from the colonic wall. The resected mass was confirmed as colonic leiomyoma. The other dog with constipation had normal CBC and biochemistry values. On survey abdominal radiographs, there was a soft tissue density round mass dorsal to the descending colon and rectum. The descending colon was displaced ventrally and narrowed by the mass. On ultrasonographs, a well-defined round heteroechoic mass compressed the colon. The mass was also pedunculated and originated from the colonic wall on surgery and confirmed as colonic leiomyoma. Two dogs recovered without any clinical signs after surgery and showed permanent resolution of the clinical signs, respectively.

A 3-year old female Poodle dog was presented with a history of anorexia, vomiting, abdominal pain and depression for 2 days. After physical and blood examination, excretory urogram(EU) and ultrasonography of the abjomen were conducted. On radiographs and ultrasonographs, dilation of diverticulum, sinus, proximal ureter of right kidney and mild dilation of left renal medullar were found. And there was some leakage of contrast agent in the proximal ureter area of right kidney. So this was diagnosed as a rupture of right proximal ureter. This dog was undertaken a surgery of nephrectomy of right kidney. On surgery, dilation of right kidney and hemorrhage, adhesion were found at the proximal ureter and some calculi were also found in the pelvis of right kidney. There were no complications after surgery.

An 11-year-old castrated male Maltese had vomiting, diarrhea, and abdominal distension for over two weeks and weight loss for several months. Clinical laboratory studies were not remarkable. Abdominal radiographs showed severe dilated intestine with a gravel sign. Colon was empty with normal diameter in the pneumocolon study. On ultrasonographs, most small bowel loops were dilated without normal peristalsis and showed abnormal thin wall. Barium contrast study revealed remarkably delayed gastric emptying and transit time up to $6^{th}$ day. On exploratory laparotomy, there were no mechanical obstruction and extra-intestinal abnormalities except severe dilated small intestine. Chronic fibrosing lymphohistiocytic leiomyositis with atrophy of tunica muscularis in the small intestines and colon was identified through full thickness biopsy and histopathology. Therefore, primary myopathic chronic intestinal pseudo-obstruction was diagnosed. This dog is survival with symptomatic treatments for eight months.

An intact male, 3-month-old, Great Pyrenees mountain dog, weighing 7.3 kg with a history of severe hematuria during 2 months was referred. Hematology showed mild leukocytosis. There were no remarkable findings in abdominal radiographs due to ingesta and gas in the gastrointestinal tracts. Ultrasonographs showed bilateral hydronephrosis, bilateral dilated and tortuous ureters, and hyperechoic sludges in the urinary bladder (UB). And a dilated cavity was identified cranial to the UB. Excretory urography and cystography were performed to examine the cause of hydronephrosis and an abnormal cavity cranial to the UB. Bilateral ureters were tortuously dilated and opened into the craniodorsal part of the UB. An abnormal cavity was connected to the UB at the left cranioventral part of the UB. Therefore bilateral ectopic ureters and urachal remnant were diagnosed.

An eight-month-old, intact female Jindo, weighing 9 kg with a one-day history of acute bloody diarrhea was referred. Plain abdominal radiographic findings included evidence of a soft tissue tubular mass within the dilated colon. In ultrasonographs, a target-like mass was identified with multiple hyperechoic and hypoechoic parallel wall layers. A barium enema showed a large radiolucent filling defect within the colon and a completely occlusive lumen. On the basis of these images, ileocecocolic and colocolic intussusception was diagnosed. Surgical manual reduction, resection and anastomosis were performed. The patient recovered normally without any complications or recurrence.

Three calves which were born in a village with similar symptoms that urine ran down along the inner femoral region were referred to Veterinary Medical Teaching Hospital, Kyungpook National University. On physical examination, there were aplasia of the penis, ventrally incomplete sheath and bifid scrotum in common. Blood cell count test and blood biochemistry test were performed and then diagnostic radiography was carried out in a case. Retrograde positive cystograph showed normal urinary bladder and no other urogenital abnormalities. The shape and size of the testes were normal on ultrasonographs, yet intact urethral wall was not detected. These cases were diagnosed as hypospadias.
