Patients with known infective endocarditis and IIAs but who remain neurologically asymptomatic should be followed by cerebral angiography

Biplane cerebral angiography

It may prove that metabolic changes are expected and normal given this broader context or other diagnostic tests may be needed such as a electroencephalograph monitoring (such as seizure detection), head CT, or cerebral angiography
to determine the cause of the observed metabolic crisis (Vespa et al.

Although conventional cerebral angiography
provides comprehensive evaluation of the carotid distribution, including accurate characterization of plaque and collateral circulation (4), the risk of neurological complications (4%) and even death (1%) has led to its relatively uncommon use (5).
The term angiographically negative SAH, often used interchangeably with NASAH, refers to the fact that conventional cerebral angiography
fails to reveal a source for the hemorrhage.
revealed that the tumor was primarily supplied by three branches of the left external carotid artery--the left posterior occipital artery, the ascending pharyngeal artery, and the posterior auricular artery--with a minor contribution from the petrous branch of the left internal carotid artery.
The diagnosis can be considered based on MR and computed tomographic angiography findings, although cerebral angiography
is considered the gold standard for suggesting the diagnosis.
