Resumo
Background: Cycas revoluta (sago palm) is a toxic ornamental plant which, when ingested, can cause hepatotoxic effects, gastrointestinal signs, and neurological alterations. Albeit rarely, C. revoluta ingestion can culminate with chronic severe hepatitis associated with hepatic fibrosis. The objective of this work is to report a case of hepatic cirrhosis consequent to ingestion of C. revoluta in a dog and describe the clinical and pathological aspects that accompany the development of chronic hepatopathy, as a way to provide information that may help diagnosis of this condition. Case: A 9-month-old male mongrel dog was presented for examination with a history of increased abdominal volume and anorexia 20 days after ingesting the seeds of Cycas revoluta. Laboratory exams revealed hypochromic microcytic anemia, neutrophilic leukocytosis, monocytosis, thrombocytopenia, decreased albumin, and elevation of the enzymes alanine aminotransferase and alkaline phosphatase. Ultrasound scanning showed presence of hepatomegaly, a heterogeneous hepatic parenchyma, and free fluid in the peritoneum. The animal was treated and was discharged from the hospital. Twenty days later, the patient returned to the hospital exhibiting prostration, vomiting, ascites, and pale mucous membranes. The alterations observed in the previous laboratory exams persisted except for thrombocytopenia, which was absent. A new treatment was administered, and the animal was discharged three days later. However, the patient returned once again exhibiting hyporexia, hemorrhagic diarrhea, and slight prostration that progressed to severe prostration, lateral decubitus and death approximately two months after ingesting the plant. Necropsy revealed a markedly poor body condition, slight icterus, limb edema, ascites and hydrothorax, and an atrophied liver with a yellowish color and an irregular, but firm, capsule surface. Additional alterations included...
