A 16 years old neutered male Miniature Dachshund with 1-year history of repetitive administration of zonisamide for treatment of epileptic seizure was presented for vomiting, anorexia and diarrhea. Serum biochemistry showed a markedly elevated ALP level. The dog died 6 days after the presentation and a necropsy was performed. Histopathologically, random, focal to extensive necrosis, formation of regenerative hepatocellular nodules surrounded by fibrous septa and proliferation of bile ducts were seen in the liver. From these findings, the hepatic lesion was diagnosed as hepatocellular necrosis with prominent regenerative reactions due to the chronic persistent liver injury. Hepatic lesions were considered to be induced by zonisamide, based on the history of continuous administration, and clinical and histopathological findings.
