Cardiogenic cerebral embolism caused by a severe hypoglycemic attack : a case report

The direct relationship between a hypoglycemic attack and cerebral infarction remains unknown. It has been reported that a hypoglycemic attack can result in takotsubo syndrome, leading to cerebral infarction. We report a case of a cardiogenic cerebral embolism caused by a hypoglycemic attack, with additional literature review. A 71-year-old woman was admitted to our hospital in a semi-comatose state due to a severe hypoglycemic attack ; she developed hemiplegia one day after admission. Magnetic resonance imaging revealed cerebral infarction in the area supplied by the left middle cerebral artery. Takotsubo syndrome was suspected based on echocardiography. We diagnosed cerebral embolism due to takotsubo syndrome, caused by the hypoglycemic attack.
