  https://www.mayoclinic.org/diseases-conditions/aneurysms/symptoms-causes/syc-20354633

  An aneurysm is a bulge or ballooning in the wall of a blood vessel. A ruptured aneurysm causes bleeding inside the body. Some people with aneurysms only need regular health checkups and imaging tests. Dr. Bendok says 1 to 2 percent of the population have aneurysms and only a small percentage of that group will experience a rupture. People who have a family history of aneurysms, have polycystic kidney disease, connective tissue disease, and people who smoke are at increased risk of rupture and should consider screening. […] A portion of these patients will go on to have a rupture. And the challenge with rupture is that it’s unpredictable. […] If a rupture happens, fast treatment can save lives.

  Most aneurysms are caused by degeneration of the vascular wall integrity. […] The commonest type of aneurysm is due to atherosclerotic degeneration and elastin deficiency within the middle (media) layer of the wall. […] Aneurysms can also be caused by bacterial infections (Salmonella, Streptococcus, Staphylococcus, E-coli, Treponema) and these are called mycotic aneurysms. […] Pseudoaneurysms or ‘false aneurysms’ are formed when bleeding from an area of the artery is contained within the soft tissue, causing a pocket of swirling blood that is in communication with the flowing artery. […] Aneurysms generally do four bad things: 1) expand, leading to a mass effect and pressure on the adjacent structures 2) rupture, bleeding, exsanguination, leading to limb loss of death 3) accumulation of clots/sediments that break off, flow along (embolize), and plugs off blood supply 4) the whole aneurysm clots off, cutting off blood supply of the artery downstream.

  INTRODUCTION […] An aneurysm is an abnormal focal arterial dilation. Pre-existing aneurysms can become secondarily infected, but aneurysmal degeneration of the arterial wall can also be the result of infection that may be due to bacteremia or septic embolization, as in the case of mycotic aneurysms. The name mycotic aneurysm was coined by Osler to describe aneurysms associated with bacterial endocarditis. These were noted to have the appearance of „fresh fungus vegetations”; however, the majority of mycotic aneurysms are caused by bacteria. Although some authors use the term „mycotic” to describe infected aneurysms regardless of etiology, we will limit the use of this term to those aneurysms that develop when material originating in the heart causes arterial wall infection and, subsequently, dilation.

The deformity can happen due to thinning of the wall, but sometimes inflammation or trauma can cause the deformity without thinning. […] Its still unclear what exactly causes aneurysms to form. However, its believed that one or a combination of the following factors may promote their development: a break down of elastic tissue within the artery, stress from blood flow through the artery, tissue changes in the artery due to increases in inflammation. […] Brain aneurysms are also more likely to happen where an artery branches into different directions. This is because arteries are naturally weaker at these locations.

  https://www.ajnr.org/content/30/1/e8

  I read with interest the review article by Drs van Rooij and Sluzewski and have some comments. […] Despite their goal to review therapeutic strategies for large and giant aneurysms, they ignored or had few comments regarding their growth mechanisms, which are essential in deciding appropriate treatment. Our knowledge of intracranial aneurysms has evolved from considering them as a focal and intraluminal disorder to seeing them as a complex condition involving arterial walls, extraluminal environment, and a long sequence of biologic events. The concept of aneurysmal vasculopathies was developed and a classification based in physiologic mechanisms was proposed to convey this complexity. […] The role played by the vasa vasorum, inflammation, and focal mural dissections in their pathogenesis is supported by clinical, pathologic, and biologic studies.

  Aortic aneurysm is found in 5 to 10 people out of every 100,000. Aneurysms are named for the place they occur in the aorta. An aortic root or ascending aortic aneurysm occurs in the part of the aorta that runs from the heart to the chest. An abdominal aortic aneurysm, which occurs below the chest, is the more common form of the disease. […] Most people walk around with aortic aneurysm and dont even know it because most aortic aneurysms dont cause symptoms, Dr. Peterson says. When concerning symptoms do occur, including ripping or tearing chest or abdominal pain, its a medical emergency. These symptoms can signal that an aortic aneurysm has weakened and ruptured, potentially causing life-threatening bleeding. […] You are at increased risk if you have a first-degree relative, such as a mother, father, brother, or sister, who has been diagnosed with an aortic aneurysm or bicuspid aortic valve (BAV) disease, Dr. Peterson says.

  An aneurysm is an enlargement or bulge in a weakened section of an artery. It can build over long periods of time and often does not present symptoms or problems until it ruptures. Once ruptured, an aneurysm can result in internal bleeding or stroke, sometimes with fatal consequences. An aneurysm most often occurs in the aorta, brain, abdomen, or knee area. […] An aneurysm can be caused by any condition that weakens an artery wall. High blood pressure exerting excessive force against the arterial wall is a common factor. Atherosclerosis, a narrowing of the arteries through the buildup of plaque caused by cholesterol, fats, and calcium, is another cause. Other causes can be an infection, wound, or genetic anomaly. […] While age, weight, smoking, and overall health can have an effect in some cases, aneurysms can occur in nearly anyone. They can also occur in any artery in the body, especially those connected to the heart, legs, kidneys, and brain.
