Background:
Primary hepatobiliary
tumors are rare in
dogs and
cats. Studies suggest a
prevalence of 0.6% in
dogs and 2.9% in
cats from all occurring
tumors.
Neoplasia in these
tissues can have hepatocellular and
bile ducts origin or even be
sarcomas or
neuroendocrine tumors. Its clinical signs are nonspecific and the
diagnosis is most often tardy or even done during necropsy. A case of
cholangiocellular carcinoma and
glomerulonephritis in a
cat is reported, addressing its clinical aspects and emphasizing the importance of an
early diagnosis. Case A mixed breed, 12-year-old neutered
cat was admitted in the
Veterinary Teaching Hospital of the Federal
University of Rio Grande do Sul treated previously without obvious improvement.
Jaundice, severe
dehydration, excessive
salivation, low body condition (score three out of nine), abdominal discomfort, and
lethargy were evident on
physical examination.
Blood tests showed neutrophilic
leukocytosis,
lymphopenia, and increased
serum levels of both
alanine aminotransferase and
alkaline phosphatase enzymes. Abdominal ultrasound examination revealed a large single mass of three centimeters of diameter, approximately, compressing the
bile ducts. Because of the severity of the
patients condition, it was hospitalized to receive supportive care. During
hospitalization, the
animal received
feeding through an esophageal tube, intravenous fluid...(AU)
