Clinical Data
70-year-old male patient:
Status post:
-
Intracranial hypertensive right basal ganglia bleed a year ago, resulting in mild left-sided hemiparesis.
-
Small left cerebellar ischemic infarction half a year ago.
Now presents with worsening of left-sided hemiparesis (left-sided facial droop, severe weakness of the upper/moderate lower limbs) and aphasia. Onset of symptoms two hours ago.
The patient had similar transient neurologic episodes in the preceding week, which improved spontaneously, then presumed to represent transient ischemic attacks (TIAs).
A non-contrast head CT, CT angiogram (CTA) of the cervical and intracranial arteries and CT perfusion (CTP) were performed (code stroke).
