Plain-English summary
A 6-year-old Shih Tzu was brought in for severe seizures that occurred in clusters. Imaging tests revealed changes in the brain and a condition called a portosystemic shunt, which can lead to a buildup of toxins in the blood affecting the brain. The dog was diagnosed with hepatic encephalopathy, a serious condition caused by liver issues. After starting treatment to lower ammonia levels in the blood, the dog's seizures improved over time.

Abstract
A 6-year-old ShihTzu presented with tonic-clonic cluster seizure. T2-weighted magnetic resonance (MR) images showed bilateral diffuse hyperintense lesions at the cerebral cortex with enlarged sulci. Computed tomography revealed a portosystemic shunt (PSS) and azygos continuation. Based on the clinical signs, blood examinations and diagnostic images, the dog was diagnosed with hepatic encephalopathy secondary to PSS. The neurologic signs were gradually improved after medical therapy for hyperammonemia. This is the first report of hyperintensity of the cerebral cortex on T2-weighted MR images associated with acute hepatic encephalopathy in a dog.
