A five-year-old spayed female Labrador retriever presented with right forelimb lameness one day earlier. Radiographs and computed tomography of the right shoulder joint revealed conspicuous enthesophytes, bone cyst, and bone fragment at the intertubercular groove. Magnetic resonance imaging showed a loss of continuity of the biceps tendon and inhomogeneous hyperintense signal of the surrounding soft tissue and moderate synovial fluid on T2- and proton density-weighted images with contrast enhancement on the postcontrast T1-weighted images. The dog was diagnosed with tenosynovitis and biceps tendon rupture with osteoarthritis based on a comprehensive evaluation of the computed tomography and magnetic resonance imaging features.

A 5-year-old neutered female Dachshund dog presented with a 3-month history of hyperthermia, skin lesions, and shifting lameness. Based on physical examination, blood tests, urinalysis, and radiographs, the dog was diagnosed with systemic lupus erythematosus. Clinical signs improved after administration of prednisolone and cyclosporine but relapsed after the prednisolone was reduced due to side effects. Oral levamisole was commenced and the other immunosuppressants were tapered over a period of 2 months and then stopped. Levamisole was retained as the sole therapy for an additional 2 months. Six months after discontinuation of all treatment, the patient remained in remission.

A 12-year-old, spayed female, Toy-poodle dog presented in progressive, pruritic carpal mass and mandibular papule. The skin lesions and enlarged superficial lymph nodes were surgically removed. According to histopathology and immunohistochemistry, the patient diagnosed as cutaneous epitheliotropic T-cell lymphoma with lymph node metastasis. Chemotherapy with L-asparaginase, lomustine and prednisolone was initiated. The patient deteriorated despite treatment and was admitted to the hospital. Blood tests revealed significant leukocytosis. Circulating large lymphocytes with convoluted and cerebriform nuclei seen in peripheral blood led to presumption of Sézary cells. Thus, considering skin, lymph nodes and blood involvement, Sézary syndrome was diagnosed.

A 7-year-old spayed female Shih Tzu dog was presented for evaluation of recurrent hypoglycemia. Serum insulin levels during hypoglycemia were 35.3 µIU/mL. Ultrasonography and computed tomography showed a mesenteric nodule between the kidney and the portal vein, but no pancreatic mass was observed. During surgery, the nodule had neither anatomical adhesions nor vascular connections to the pancreas. Pancreatic inspection and palpation revealed no abnormalities. Hypoglycemia improved after resection of the nodule. Histopathological examination confirmed the nodule to be an islet cell carcinoma. Although extremely rare, ectopic insulinoma should be considered as a possible cause of insulininduced hypoglycemia in dogs.

An 11-year-old spayed female Maltese dog presented with mass in oral cavity. On conscious oral examination, the right maxillary canine tooth was not visible, and a lesion has been suspected of mass existed in canine tooth area. The adjacent maxillary first premolar was buried in the lesion, with a little part of the tooth exceptions. On radiographic examination, the canine tooth was buried horizontally in the lesion, and the root part was adjacent to the first premolar tooth. Extraction was performed for a treatment. When the lesion was incised, the canine tooth was horizontal with the concave surface facing the palatal, and formed double teeth by fusing with the premolar tooth at the roots parts of the teeth. This report described the double teeth in the dentigerous cyst rarely reported in dogs.

A 6-month-old female Border Collie presented with a history of collapse after strenuous exercise. The dog was normal between episodes but experienced loss of focus and ataxia after exercise. This is particularly noticeable under hot weather conditions. No remarkable findings were observed in the diagnostic tests. Based on these results, the patient was tentatively diagnosed with Border Collie collapse (BCC). After exercise restriction, the dog had no episode of collapse and remained clinically well with no signs until the follow-up period of 8 months was complete. To our knowledge, this is the first case report of BCC in South Korea.

Importance: This case report presents the successful surgical removal of a pheochromocytoma in a dog using indocyanine green (ICG) fluorescence imaging. Case Presentation: A 10-year-old, 6.87 kg, spayed female poodle was referred for an abdominal mass and eight episodes of vomiting. Computed tomography revealed masses in the spleen and left adrenal gland. Based on the plasma normetanephrine levels, the patient was diagnosed with pheochromocytoma. Subsequently, a total splenectomy and left adrenalectomy were performed. A dose of 5 mg/kg ICG was administered intravenously 24 h prior to surgery. Using ICG allowed visualization of tumor margins, aiding in complete resection and minimizing anesthesia-related risks. Conclusions and Relevance: No evidence of recurrence or metastasis has been observed for 12 months. To our knowledge, this is the first report of the surgical removal of a pheochromocytoma using intraoperative ICG imaging in veterinary medicine. This case highlights the efficacy of ICG fluorescence imaging as a valuable tool for the surgical management of adrenal tumors in veterinary medicine.

A 2-year-old female, 3.8kg weight, mixed-breed dog was presented for a 10-day history of vomiting and anorexia. The dog was diagnosed with pelvic fracture by vehicular accident at a local animal hospital before 2 months, but fracture did not reconstructed. After 2 months, the dog suffered from intermittent vomiting and anorexia. On barium contrast, we diagnosed the dog as intestinal obstruction. Consequently, we were found obstruction by strangulation and adhesion of intestine at the fracture site through the operation. At present after 18 months of surgery, general physical condition of the dog is good.

A four month old, intact female Jindo dog presented to the Veterinary Teaching Hospital of Kangwon National University with collapse. Physical examination revealed a heart rate of more than 200 beats per minute. Blood tests showed mild anemia and mild neutrophilia, while thoracic radiography and ultrasonography revealed no remarkable findings. Electrocardiography showed ventricular premature complexes (VPCs). The dog was diagnosed with congenital ventricular tachyarrhythmia. The condition was improved by lidocaine infusion. After 10 days, the dog was discharged from the hospital with a prescription of atenolol, pimobendan, diltiazem, furosemide, spironolactone, and L-carnitine. This dog is still alive after 31 months. However, progressive cardiac remodeling was confirmed on radiography and ultrasonography. Congenital ventricular tachyarrhythmia is rare in dogs, and the prognosis of reported cases is poor. This report describes the long-term successful management of a dog with congenital ventricular tachyarrhythmia.

Mesenteric torsion was diagnosed in a 2-year-old, spayed female Miniature Schnauzer. The patient was presented with acute depression, vomiting, lethargy and hematochezia. On physical examination, severe dehydration, tachycardia, tachypnea, weak femoral pulse, delayed capillary refill time and pale mucous membrane were found and the dog was in shock. Radiography and ultrasonography revealed intestines distended with gas, ascites and the "C" shaped distended intestine. Medical treatments including fluid therapy, analgesics, antibiotics and lidocaine for reducing reperfusion injury were applied. And then, the mesenteric torsion was definitively diagnosed through exploratory laparotomy and intestinal resection and anastomosis were performed. The dog made an uneventful recovery and was free of clinical sign one week after surgery. Mesenteric torsion is an unusual and life-threatening disease in dogs. It has usually been described in the middle and large breed dogs, especially German Shepherds. However, the mesenteric torsion should be included in the differential diagnostic lists for acute abdomen even in small breed dog. The mortality rate of mesenteric torsion can be reduced through prompt diagnosis, proper preventive therapy for shock and reperfusion injury and emergency surgery.
