| Summary points: | This report features 2 cases -- a 63-year-old man and a 67-year-old man -- with hyperglycaemia and ketoacidosis due to diabetes decompensation and chronic alcoholism who develop Wernicke encephalopathy before their hospital admission. Symptoms, physical and neurological examinations, laboratory data, abdominal ultrasound with image, neuromuscular analysis, MRI with image, and lumbar puncture are described. The authors describe their treatment approach and discuss the presence of Wernicke encephalopathy in alcoholics with diabetic ketoacidosis, suggesting that metabolic decompensation is essential in the onset of the disease. |
