What would be the next step for diagnostic work-up?
A CTA of the cervical and cranial vessels should be performed to narrow possible causes of bleeding.
Large intraparenchymal hemorrhage in the right frontal lobe, extending near the basal nuclei with narrow zone of surrounding hypodensity, most likely representing edema.
Large volume subarachnoid hematoma in most sulci and all cisterns.
Intraventricular hematomas in both lateral ventricles, the third and fourth ventricle.
Widening and hydrocephalic configuration of supratentorial ventricles, indicative of obstructive hydrocephalus due to blood in the aqueduct.
