There is evidence of intracranial/extradural aneurysm: petrous canal cavernous sinus, sub clinoidal space, lower ICA ophthalmic segment, or superior hypophyseal segment. This can be any type, saccular aneurysm, arteriosclerotic giant aneurysm, or blister aneurysm. [Yes/No]
There is evidence of intracranial/intradural saccular or giant arteriosclerotic aneurysm(s): upper ophthalmic ICA segment for true ophthalmic, dorsal ophthalmic variant, or ICA apex aneurysms. [Yes/No]
There is evidence of intracranial/intradural saccular aneurysm: communicating ICA segment for P-com aneurysm. [Yes/No]
There is evidence of intracranial/intradural saccular aneurysm: choroidal ICA segment for anterior choroidal aneurysm. [Yes/No]
There is evidence of intracranial/intradural saccular aneurysm: caudal P-com/P1 PCA junction aneurysm. [Yes/No]
There is evidence of intracranial/intradural saccular aneurysm: ICA vertex, or lenticulostriate (off M1 or A1), or anterior temporopolar aneurysm (off M1/2). [Yes/No]
There is evidence of intracranial/intradural saccular aneurysm: A1-2 segment for anterior communicating aneurysm. [Yes/No]
There is evidence of intracranial/intradural saccular aneurysm: distal ACA for pericallosal aneurysm. [Yes/No]
There is evidence of intracranial/intradural saccular aneurysm: M1-2 segment for lateral frontotemporal, or MCA trifurcation aneurysm. [Yes/No]
There is evidence of intracranial/intradural saccular aneurysm: basilar apex aneurysm. [Yes/No]
There is evidence of intracranial/intradural saccular aneurysm: PCA-SCA junction aneurysm. [Yes/No]
There is evidence of intracranial/intradural saccular aneurysm: PICA origin aneurysm. [Yes/No]
There is evidence of saccular aneurysm complexities including daughter aneurysms and wide neck (vs fundal width), aneurysm neck involvement of parent artery, local dissection of parent artery. [Yes/No]
There is evidence of major vessel vasospasm (minimal, moderate, or advanced). [Yes/No]
There is evidence of a bleb/blister type aneurysm (usually off ICA ophthalmic segment or dorsal side of A-com or basilar apex). [Yes/No]
There is evidence of a major artery spontaneous distal fusiform aneurysm. [Yes/No]
There is evidence of intracranial/intradural dissecting aneurysm: vertebral or carotid dural penetration site. [Yes/No]
There is evidence of intracranial/intradural dissecting aneurysm of distal artery branches: consistent with saccular appearing dissection or mycotic source. [Yes/No]
There is evidence of a distal pial artery inflammatory tubular aneurysms, especially M2-4, P2-4 arteries. [Yes/No]
There is evidence of aneurysms associated with vascular anomalies: arterial fenestrations, trigeminal anomaly, or any other arterial anomaly. [Yes/No]
There is evidence of major vessel atherosclerotic sacculo-fusiform aneurysm.
[Yes/No]
There is evidence of significant arteriosclerotic dolichoectasia. [Yes/No]
There is CT perfusion evidence of dysautoregulation (mixed vasospasm and downstream vasodilatation from collaterals). [Yes/No]
Other abnormalities [Yes/No]
