Abstract
|
|
|
|
Non-ketotic hyperglycemia (NKH) is a clinical syndrome comprising hyperglycemia, serum hyperosmolality and intracellular dehydration with little or no ketoacidosis. NKH has been associated with a variety of neurological manifestations such as seizure, choreoathetosis, hemiballismus, and alteration of mental status. The most common type of seizure associated with NKH is focal or generalized motor seizure, but it can be manifested as visual seizure characterized by flashing lights, visual hallucination, photopsia and homonymous hemianopsia. We report a patient showing reversible quadrantanopsia and subcortical T2 hypointensity in the occipital lobe after visual seizure associated with NKH.
