A 4-year-old neutered female domestic shorthair cat weighing 5.1 kg was referred to Jeju National University Hospital with acute onset respiratory distress, weakness, and anorexia. The patient had a history of stressful antecedent events that involved bullying by a newly introduced cat. Thoracic radiography and echocardiography revealed a stage C hypertrophic cardiomyopathy phenotype based on the American College of Veterinary Internal Medicine classification system with pulmonary edema, pleural effusion, and pericardial effusion at the same time. The patient was treated with furosemide, pimobendan, and rivaroxaban. Pericardiocentesis was performed because pericardial effusion was identified. Reevaluation after 30 days revealed a normal respiratory rate on physical examination, normal cardiac shape on thoracic radiographs, and normal cardiac measurements on echocardiography. The patient was tentatively diagnosed with transient myocardial thickening (TMT) and all medications were discontinued. Six months after the initial hospitalization, the cat continued to do well without any clinical signs or left ventricular wall thickening. This case is the first report describing feline TMT in Korea. Moreover, it involves a rare case in which pulmonary edema, pleural effusion, and pericardial effusion, which induce cardiac tamponade, occurred simultaneously due to TMT-related congestive heart failure.

3년령 한국 집고양이가 갑작스럽게 발병한 간헐적 경련 증상을 주 증상으로 내원하였다. 신체검사상 구리 빛 홍채가 관찰되었고, 양안에서 위협반사 소실이 관찰되었다. 혈액학 검사와 혈청 화학 검사에서 경증의 적혈구 증가증과 심한 소적혈구증, 증가된 ALT 활성도가 확인되었으며, 추가로 실시한 간기능 평가에서는 담즙산염 농도와 암모니아 농도가 증가하였다. 방사선 검사에서 간 내 다수의 결절이 관찰되었고, 간외성 션트 혈관을 발견하였으며, 추가로 실시한 컴퓨터 단층 촬영을 통해 복합 간외션트를 확인하였다. 고양이는 션트 혈관에 대한 외과적 처치술을 받기 위해 증상 완화를 위한 디아제팜과 락툴로즈를 투여하였으나 경련이 심화되었고, 심장 정지가 와서 폐사하였다.

A 7-year-old castrated male domestic short-hair cat presented with anorexia, constipation, depression, and voice alteration. Physical and neurological examinations revealed hyperthermia ($40.5^{\circ}C$), ventroflexion of the neck, reduced responses to external stimuli, generalized muscle weakness, and exercise intolerance. Thoracic radiographs revealed the presence of a cranial mediastinal mass. The history, clinical signs, and other examination results were compatible with acquired myasthenia gravis (MG). Acetylcholine receptor (AChR) antibody titers were determined to confirm MG and the serum AChR antibody concentration was 1.24 nmol/L (reference interval, < 0.3 nmol/L). This is the first diagnosis of acquired MG in a cat in Korea.

A 10-year-old castrated male Domestic Shorthair cat visited a veterinary medical teaching hospital for emergency dyspnea. The cat was hypoxic and hypotensive, and stridorous respiration was remarkable. Visual inspection confirmed laryngeal paralysis and a lack of mobility of the left larynx. Megaesophagus, aspiration pneumonia, cranial mediastinal mass, and positive Tensilon test results using neostigmine were observed, indicating acquired myasthenia gravis secondary to thymic neoplasia. After 10 minutes of neostigmine 0.02 mg/kg IV administration, laryngeal paralysis and dyspnea resolved. Histopathlogical examination for the cranial mediastinal mass after surgical resection confirmed malignant thymoma. Here, we report a case of acquired myasthenia gravis in a cat with a malignant thymoma that presented with life-threatening dyspnea due to laryngeal paralysis. Feline laryngeal paralysis is uncommon, and myasthenia gravis, a cause of laryngeal paralysis in cats, has not yet been reported. Myasthenia gravis should be considered in cats with laryngeal paralysis.

A seven-year-old, castrated male, Korean domestic shorthair cat was referred because of a kidney abnormality. Radiography revealed left renal agenesis and right kidney enlargement. Ultrasonography and computed tomography (CT) showed amorphous calcified materials in a cyst-like lesion of the right kidney. In the excretory phase of the CT images, the lesion was opacified with contrast materials, indicating communication with the collecting system. Based on these findings, the cat was diagnosed with a calyceal diverticulum. A calyceal diverticulum may cause various clinical symptoms related to the urinary system. The excretory phase of CT is useful for diagnosing a calyceal diverticulum.

6개월령의 한국토종단모고양이가 발열, 빈호흡, 식욕부진, 체중감소로 내원하였다. 고양이는 10일 전 Fellocel$^{(R)}$ 백신을 접종받은 이후 증상을 보였다. 신체검사 결과 공막의 황달과 호흡곤란을 호소했다. 혈액혈구검사와 혈액화학검사에서 빈혈, 혈소판감소증, 백혈구증가증, 고빌리루빈혈증이 관찰되었다. 혈액도말 검사와 기타 검사를 통해 심한 용혈을 확인할 수 있었고 고양이 용혈성 빈혈을 감별진단 하기위해 Erhlichia, Hemobartonella, FeLV, FIV, Anaplasma PCR 검사를 의뢰하였다. PCR 검사 결과 Mycoplasma haemofelis 특이 208 bp의 양성밴드가 확인되었고, 다른 질병은 음성으로 진단되었다. 고양이는 4주 동안 Doxycycline을 사용하였고 급성기 1주 동안에는 prednisolone을 같이 사용하였다. 임상증상은 약물투여 4일째부터 호전되기 시작하였고 이후 PCR 재검을 통해 완치를 확인하였다. 이것은 M. haemofelis 감염 고양이의 진단을 확인하고 완치한 국내 첫 증례이다.

A 6-year-old male domestic shorthair cat was referred to Gyeongsang National University Animal Medical Center for labored breathing. According to the patient's history, the client had fed him commercial dog foods. The patient's hematological, radiographic, and echocardiographic examinations were evaluated for diagnosis. Echocardiography results showed marked dilations of ventricles and atriums and mitral regurgitation. A systolic dysfunction was detected. Plasma taurine concentration was lower than the reference range. Based on these results, the patient was diagnosed with feline dilated cardiomyopathy associated with taurine deficiency. Treatment included feline commercial foods, taurine, digoxin, furosemide, and clopidogrel. Digoxin was changed to pimobendan when normal blood pressure was achieved. Clinical signs improved gradually and no abnormalities were detected on echocardiograms at 10 weeks following onset of treatment.

A 2 months old female Korean domestic shorthair cat weighing 1.2 kg was come to hospital because of respiratory discomfort and lethargy. Heart sounds was more intense and clear on the right side than the left. On radiographic views, loss of the normal diaphragm line, undistinguishable shadow of heart, shadow of gas-containing intestines could be observed in thoracic cavity. Diaphragmatic herniorrhaphy was performed by using propofol 8 mg/kg IV and isoflurane without any complication. On 7th day after the operation, almost all the clinical signs and radiographs including diaphragmatic line, cardiac silhouette, liver and small intestines were turned to normal.

Two Domestic Korean Shorthair cats presented with dyschezia and vomiting. Computed tomography revealed a colonic mass with calcification and lymph node metastasis in case 1, and a small intestinal mass with disseminated mesenteric metastasis and calcification in case 2. Histopathology revealed intestinal adenocarcinoma with osseous metaplasia. Case 1 died two months after surgery from distant metastasis; and case 2 showed no metastasis for five months but presented with anorexia, euthanized seven months after diagnosis. Metastatic intestinal adenocarcinoma with bone formation should be considered as differential diagnosis for calcification on imaging, and lymph node metastasis at diagnosis may indicate poor prognosis.

A 8 months old, female domestic Shorthair cat with long-term signalment of anorexia, lacrimation, uveitis and coughing was submitted to the Pathology and Diagnosis Reference Division, NVRQS, Korea, for necropsy. Main gross lesions were characterized by ascities, some grayish-white nodular formation and fibrous adhesion on the surface of visceral organs including liver and kidney. Principle histopathological findings were fibrinous serositis, multifocal granuloma and necrosis, vasculitis, perivasculitis in various pharenchymal organs. Paraffin-embedded tissue sections taken from most of organs with granulomatous lesions were confirmed specific reaction to the monoclonal antibody of feline infectious peritonitis virus in the cytoplasm of many infiltrating macrophages by immunohistochemistry. The report was to describe the pathological lesions of the first naturally-occuring FIP case in companion cat of Korea.
