Early hyperacute ischemic stroke
Discussion:
There is extensive early hyperacute (0-6 hours) non-hemorrhagic infarction as demonstrated above with negative T2 FLAIR imaging. The study was prematurely curtailed due to the instability of the patient during image acquisition and an intra and extracranial angiogram could not be completed.
The patient suffered a cardiac arrest and resuscitation was unsuccessful.
The multifocal sites of hyperacute infarction suggest a possible embolic etiology.
The MRI findings and the rapidity of the patient's clinical deterioration after presentation to the emergency department were unexpected.
