A 2-year-old, spayed female, Korean domestic short-hair cat was presented with depression and vomiting. The patient had history of weight loss lasting seven months. Physical examination revealed icterus in the pinna, oral mucosa, and sclera. Based on ultrasonography and computed tomography, tentative diagnosis was extrahepatic biliary tract obstruction with acquired portosystemic shunt (PSS). Tumor or inflammation of hepatobiliary system was suspected as the cause of obstruction of the common bile duct. But it could not be determined without biopsy. The severely dilated cystic duct was considered to cause portal hypertension and secondary multiple PSS. The patient expired without histopathologic examination.

A 5-year-old intact female Persian cat was referred with anorexia and vomiting. Physical examination revealed icterus in the pinna, oral mucosa, and sclera. Ultrasonography revealed several findings including uniformly hyperechoic hepatic parenchyma compared to adjacent falciform fat, increased attenuation of the ultrasound beam, and poor visualization of intrahepatic vessel borders. Computed tomography revealed hypoattenuation of the hepatic parenchyma with a radiodensity value of-60 Hounsfield units. The adjacent intrahepatic vessels appeared hyperattenuated relative to the hepatic parenchyma as if the vessels were contrast-enhanced. Based on ultrasonography and computed tomography results, the cat was tentatively diagnosed as feline hepatic lipidosis.

An 11-year-old, castrated male dog presented with a 3-month history of cough and depression. Auscultation revealed systolic murmur and thoracic radiographs showing enlargement of both the atrium and left ventricle. Echocardiography showed thickened mitral valve and moderate-to-severe left atrial enlargement. Additionally, M-mode echocardiography showed symmetric left ventricular wall thickening and systolic anterior motion of the mitral valve, while Doppler imaging revealed high velocity turbulent flow through the left ventricular outflow tract. Based on echocardiography, this case was diagnosed with hypertrophic obstructive cardiomyopathy. After 5 months, the dog was clinically static in radiography and echocardiography.
