CT angiography showing aneurysm measuring 2.6 mm in diameter at the ACOM (anterior communicating artery). Once suspected, intracranial aneurysms can be diagnosed radiologically using magnetic resonance or CT angiography. But these methods have limited sensitivity for diagnosis of small aneurysms, and often cannot be used to specifically distinguish them from infundibular dilations without performing a formal angiogram. The determination of whether an aneurysm is ruptured is critical to diagnosis. Lumbar puncture (LP) is the gold standard technique for determining aneurysm rupture<unk><unk> . Once an LP is performed, the CSF is evaluated for RBC count, and presence or absence of xanthochromia.
