Alveolar Echinococcosis in 11-Month-Old Dog-Clinical Case.

In the present work, we describe the clinical-pathological case of an 11-month-old Border Collie dog, which was presented by its owner to a private veterinary clinic for the purpose of determining the diagnosis and subsequent therapy. The owner reports anamnestic data of abdominal enlargement, persistent apathy, fatigue, and vomiting. A complete examination of the patient was performed, consisting of clinical, hematological, and biochemical blood tests, X-ray, and USG examinations. Based on the findings, a probatory laparotomy was indicated, during which a large multi-lobular cystic irregular mass was detected, affecting the entire liver parenchyma, including macroscopic metastatic foci of the omentum and diaphragm. Due to the inoperable finding, the patient was humanely euthanized during the surgical procedure. Subsequently, an autopsy was performed with the collection of samples for histopathological and PCR examination of the tissue. Serological examination was also performed. The results confirmed a rare generalized form of alveococcosis () in the dog as an intermediate host.
