A middle-aged man with type 2 diabetes was brought to hospital with a history of loss of consciousness for an unknown period of time. He had refractory hypotension and hypoglycaemia. A magnetic resonance imaging scan showed an infarct in the splenium of the corpus callosum (Figure). The splenial infarct resembled a “boomerang”, which is characteristic.1

Strokes involving the splenium of the corpus callosum are associated with hypoperfusion,2 and can be seen in association with metabolic changes such as hypoglycaemia, hyponatraemia, hypernatraemia, and renal failure.1
