"Unruptured intradural aneurysms are often managed conservatively, with recommended regular follow-up with MRA, however follow-up timing is still debated 16. The American Heart Association/American Stroke Association (AHA/ASA) recommends initial follow-up study at 6-12 months and then yearly or every other year 16. Follow-up can be continued as long as treatment remains a valid option 16."

"As such management will vary according to local experience, the location and appearance of an aneurysm, patient demographics, etc. Risk models include the PHASES risk prediction score and those based on the ISUA-II 8 and UCAS 9 trials. Management options include endovascular occlusion with coils, flow diversion devices, endosaccular flow disruption devices, or surgical clipping."
"Endovascular coiling is graded with the Raymond–Roy Occlusion Classification (RROC) scheme."
"In follow-up imaging of treated aneurysms 3D-TOF has high sensitivity (88%) and specificity (94%) for detecting dome aneurysm recanalisation (with slightly lower performance for neck recanalisation), regardless of the type of endovascular treatment (e.g. coiling vs stent) 16. Susceptibility artifacts may limit follow-up assessment 16. In these cases CE-MRA may be a better alternative 16."
"Hp: perpendicular height measured as the largest perpendicular distance from the plane between aneurysm neck and dome"
"W: width of the aneurysm (longest diameter perpendicular to Hp)"

"Saccular cerebral aneurysms are most often asymptomatic until rupture (see ruptured saccular aneurysm), at which point they usually result in subarachnoid haemorrhage (e.g. thunderclap headache, reduced conscious state), with or without associated intracerebral haemorrhage and/or subdural haemorrhage (rarely, in up to 8% of cases) 12,13. Occasionally larger aneurysms (e.g. giant cerebral aneurysms) will result in symptoms without (or prior to) rupture, such as those from mass effect 12."
