Plain-English summary
A 5-year-old male dog had severe seizures and low blood sugar, which led to brain damage known as hypoglycemic encephalopathy. Imaging tests showed changes in the brain, particularly in the left temporal lobe, indicating damage. Over time, the affected area was replaced by fluid. This case highlights how advanced imaging can help diagnose brain issues in dogs that suffer from low blood sugar and seizures.

Abstract
We describe a 5-year-old castrated male dog suspected hypoglycemic encephalopathy that was evaluated by using diffusion-weighted imaging (DWI). The dog experienced hypoglycemia after prolonged generalized and continued partial seizures. In the acute phase, DWI showed hyperintensity in the left temporal lobe. After about a month, DWI maintained hyperintensity, and left middle cerebral artery dilation was noted on magnetic resonance angiography (MRA). In the chronic phase, the left temporal lobe lesion was replaced by cerebrospinal fluid. In humans, it was reported that cortical laminar necrosis (CLN) with hypoglycemic encephalopathy presents hyperintensity in the cerebral cortex on DWI and increased vascularity of the middle cerebral artery branches on MRA. In conclusion, DWI has detected CLN in a dog suspected hypoglycemic encephalopathy.
