Plain-English summary
A 10-year-old male Boxer in Missouri was brought to the vet with a swollen belly and worsening health. An ultrasound showed a large mass in the liver, and unfortunately, the dog was euthanized. A postmortem exam revealed that the liver was largely replaced by a mass consistent with alveolar echinococcosis, a serious infection caused by a type of tapeworm. This case is notable as it's only the second confirmed case of this infection in dogs in the contiguous United States, highlighting a significant health risk for both pets and people.

Abstract
A 10-y-old, castrated male Boxer dog that was born and had lived in Missouri without any travel history to other states, except for a few trips to Kansas, was presented with a distended abdomen and declined health. Ultrasonographic examination revealed a large hepatic mass, and the dog was euthanized. A postmortem examination revealed that the left liver lobes were largely replaced by a white-to-tan multilobular mass with a cobblestone surface. The lesion also involved the diaphragm. Histologically, hepatic architecture was effaced by large areas of necrosis with numerous, ≤0.2-cm, cystic structures that stained positively with periodic acid-Schiff stain and contained calcareous corpuscles. Gross and microscopic hepatic lesions were compatible with alveolar echinococcosis (AE) caused by. PCR examination confirmed, and results from genotyping were consistent with the E4 haplotype. To our knowledge, this is only the second canine AE case and the third pet dog that has been confirmed to be infected byin the contiguous United States.is a serious health risk for both pet dogs and humans.
