Occipital seizures and persistent homonymous hemianopia with T2 hypointensity on MRI in nonketotic hyperglycemia.

Introduction: Nonketotic hyperglycemia (NKH) is known to cause focal motor or secondarily generalized seizures. Occipital seizures in NKH are seldom reported, especially with visual hallucinations and persistent homonymous hemianopia (HH) with characteristic radiological and electroencephalographic (EEG) findings.

Summary: Our patient was a middle-aged man who presented with a new onset, single episode of generalized tonic-clonic seizure and NKH.
