Necropsy brain and liver tissue from a case of neurologic alveolar echinococcosis in postpartum zoo-housed gorilla, the Netherlands, 2024. A) Cut surface of the cerebrum. Right hemisphere contains a 3.5-cm diameter, space-occupying tissue mass with ill-defined borders and secondary dislocation of preexisting structures. B) Surface of the liver. The parenchyma is largely replaced by multiple variably sized confluent nodules.
