Abstract:
A 4-year-old female border collie was presented with haemoabdomen following the rupture of a hepatocellular carcinoma. After referral for ongoing elevation of alanine aminotransferase and alkaline phosphatase, the dog was found to have marked vacuolar hepatopathy due to glycogen accumulation within the liver, fasting hypoglycaemia and hyperlactataemia, and a negative response to glucagon stimulation testing. These changes were strongly suggestive of glycogen storage disease type 1a. Based on our literature search, this report documents the first adult canine to be diagnosed with suspected glycogen storage disease type 1a.
