A 2-year-old female Pekingese dog was presented with primary complaints including exercise intolerance and neurological sign associated with hepatic encephalopathy. The major findings in clinical examination included an intermittent seizure, a slow heart rate with pulse deficit, leukocytosis and anemia in hemogram, elevated pre- and post-prandial serum bile acid and hepatic enzymes, hypoproteinemia, coagulopathy, ammonium urate crystaluria and bilirubinuria. Diagnostic tests revealed an intrahepatic portosystemic shunt complicated with a second degree atrioventricular block and QT prolongation. The case was successfully treated with a transvenous coil embolization. Clinical signs were gradually improved and cardiac bradyarrhythmia disappeared. This case is a rare case of intrahepatic portosystemic shunts complicated with a cardiac bradyarrhythmia in a small breed dog fixed by a transvenous coil embolization.

An 8-year-old spayed female Maltese (2.5 kg of body weight) presented with the primary complaint of loud heart murmur and exercise intolerance. Diagnostic imaging revealed severe pulmonic stenosis (peak velocity 5.2 m/s) with right ventricular hypertrophy. The dog revisited after 2 years, at which time, diagnostic imaging revealed severe biventricular hypertrophy, dynamic left ventricular outflow tract obstruction, left atrial dilation and pulmonary hypertension with worsened pre-existing pulmonic stenosis. Postmortem investigation revealed hypertrophic cardiomyopathy and regional myocardial infarction. The case was diagnosed as hypertrophic cardiomyopathy secondary to severe right and left ventricular outflow tract obstruction.

A 12-year-old female Cocker Spaniel (7.5 kg of body weight) was presented for resection of a mammary gland tumor. During surgery, the heart rate was remarkably decreased due to a second-degree type I atrioventricular block. Atropine (0.05 mg/kg) was administered to increase the heart rate. Although the heart rate was elevated, atrial bigeminy occurred and persisted until the dog fully recovered from general anesthesia. These results highlight the possibility of atrial bigeminy caused by atropine administration during anesthesia.

A 6 year-old, spayed female, Maltese dog was presented with precordial thrill and mild coughing. Thoracic auscultation revealed a grade V/VI systolic murmur with maximal intensity over the left apex characterized by musical murmur. Echocardiography revealed mild myxomatous degeneration of mitral valve and ruptured chordae tendineae. Musical murmur was produced due to the vibration of ruptured piece of chordae tendineae along with regurgitant flow. After treatment with furosemide and ramipril, clinical signs resolved and precordial thrill reduced. This case report describes typical clinical signs and phonocardiogram of musical murmur in a dog with acute chordae tendineae rupture.

A 7-year-old, spayed female Chihuahua with dyspnea, intermittent cyanosis, and dermal plaques was diagnosed with hyperadrenocorticism. Thoracic radiographs showed markedly hyperdense alveoli in multiple lung lobes. Computed tomography (CT) images showed lung mineralization confined to the lung parenchyma and pituitary macroadenoma. Pulmonary mineralization secondary to hyperadrenocorticism is commonly found on histopathologic examination. However, those lesions are rarely identified radiographically. We describe obvious pulmonary mineralization secondary to hyperadrenocorticism found on radiographs and present the first report regarding CT imaging of the mineralization. Pulmonary mineralization should be considered when a dog affected by hyperadrenocorticism shows diffuse lung mineralization on radiographs.

The pathogenesis of pancreatic pseudocyst is still not understood. A 5-year-old, 24-kg intact female Shetland Sheepdog was presented with anorexia and vomiting. Diagnostic imaging tests revealed that the left limb of the pancreas was thickened and contained two cystic lesions ($6.3{\times}5.6{\times}4cm^3$ and $3.5{\times}4.6{\times}5.5cm^3$). During the laparotomy, lesions were opened with de-roofing of superabundant tissue, and omentalization was performed. The dog recovered uneventfully after surgery and was discharged on postoperative day 12. Histopathologically, it was diagnosed as chronic pancreatic pseudocyst. This case report describes the diagnosis and successful omentalization of pancreatic pseudocysts in a dog.

A 8 months old female dog with the combination of a fracture of the proximal tibia (Salter-Harris type I) with an avulsion of the tibial tuberosity was repaired with cross intramedullary pin for proximal tibial physeal fracture, and intramedullary pin combined with tension band wire for avulsion fracture of tibial tuberosity, resulted in complete healing. At 45 days after operation, on the radiological views, there was premature closure of growth plate of proximal tibia and tibial tuberosity, but at 7 months no developing growing deformities.

A 14-year-old intact female Yorkshire terrier was presented with a 2-month history of shivering, intermittent pelvic limb weakness and collapse. Biochemical abnormalities revealed inappropriately increased serum insulin concentration with persistent hypoglycemia. Abdominal ultrasound revealed multiple various sized nodules in liver and fine-needle aspirates of the nodule showed typical neuroendocrine cells with high cellularity. Computed tomography (CT) revealed well-defined hyperattenuating mass in the right pancreatic lobe with homogenous enhancement. CT findings were consistent with a pancreatic tumor with malignant metastasis. Treatment was initiated with low-dose prednisolone and toceranib phosphate. The dog was maintained stable with no more progression of clinical signs and it is worth to try toceranib phosphate in a dog with metastatic insulinoma for improving the quality of life.

A 12-year-old, intact female Jindo was referred to our clinic due to the enlargement of all lymph nodes, as well as severe dyspnea. All palpatible lymph nodes were highly swelling and enlargement. The dog was diagnosed as end stage of multicentric lymphoma with multi-organ metastasis. In addition, the dog was diagnosed as having a pulmonary thromboembolism via computed tomography (CT) and D-dimer concentrations and prothrombin time (PT) results. This case report describes that lymphoma can be associated with pulmonary thromboembolism which is life threatening complication in dogs. The present case was managed successfully with chemotherapy and antithrombotic treatment.

A 13-year-old, spayed, female Chihuahua dog was referred for evaluation of fever, lethargy, and dyspnea. Hematologic evaluation revealed severe neutropenia, thrombocytopenia, and mild anemia. The dog had been undergoing phenobarbital therapy for the past 7 weeks because of generalized seizures due to meningoencephalomyelitis of unknown etiology. After ruling out other possible causes of cytopenias, a tentative diagnosis was made of drug-induced blood cell dyscrasia. The neutropenia and thrombocytopenia resolved after discontinuation of phenobarbital (8 days and 15 days after discontinuation, respectively). This is the first case report in Korea to demonstrate blood dyscrasia associated with idiosyncratic adverse effects of phenobarbital.
