Sander A2 - Lee, Kiwon Y1 - 2012 N1 - T2 - The NeuroICU Book AB - The patient is an 83-year-old, right-handed woman with a past history of type 2 diabetes, hypertension, hyperlipidemia, and asthma who presents 10 days after experiencing an episode of right eye visual loss and left-sided hemiplegia lasting approximately 5 minutes, with spontaneous resolution. Given the transient nature of her symptoms, the patient did not seek medical care, but saw her primary care physician several days later, who subsequently ordered a magnetic resonance image/magnetic resonance angiogram (MRI/MRA) for further evaluation. She was sent to the emergency department (ED) when the scan was notable for subacute infarct in the right frontal cortex (Figure 23-1) and an absence of flow-related signal in the right common carotid bifurcation, highly suggestive of carotid stenosis (Figure 23-1). In the ED, the patient was in no acute distress, her vitals were stable, and her physical examination was notable for mild left facial asymmetry but an otherwise benign neurologic examination.
