Magnetic resonance imaging changes in a 69-year old man with hypoglycemia induced brain injury: case report and literature review.

We present the case of a 69-year old man who was brought to the hospital after being found unconscious; last seen at baseline 9 hours prior. On admission he was found to be severely hypoglycemic and received prompt glucose administration, with no immediate neurological improvement. Stroke was suspected. A brain MRI revealed abnormal hyperintense signal involving the head and tail of the left hippocampus. After close neurological monitoring and supportive care in the ICU, his condition improved over time, leaving no residual focal deficits. This case highlights the presence of MRI changes in patients with severe hypoglycemia as it happens in hypoglycemic coma.
