Summary

Hypoglycaemic encephalopathy is a feared complication in the management of patients with diabetes mellitus. We report on a 73-year-old woman with type 1 diabetes managed with an insulin pump who presented unresponsive after an inappropriate insulin bolus. The patient had minimal improvement in her neurological status over 8 days. After administration of 1 g intravenous methylprednisolone, she had dramatic neurological improvement including successful extubation and discharge from the intensive care unit. Steroid responsive encephalopathy is increasingly recognised in practice and literature. However, to the best of our knowledge, this is the first case of hypoglycaemic encephalopathy that responded to high-dose steroids.
