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 …

William Osler first used the term "mycotic aneurysm" in 1885 to describe a mushroom-shaped aneurysm in a patient with subacute bacterial endocarditis. This may create considerable confusion, since "mycotic" is typically used to define fungal infections.

2023年7月10日 · A mycotic aneurysm is an infection of vessel wall which can be bacterial, fungal, or viral in origin; they are a rare but severe complication of systemic infection and atherosclerosis, which often presents multiple diagnostic and therapeutic challenges.

2025年1月2日 · Mycotic aneurysms are aneurysms arising from infection of the arterial wall, usually bacterial. It is a complication of the hematogenous spread of bacterial infection, classically from the heart. Mycotic aneurysms are thought to represent only a minority of (0.65-2.6%) of all aortic aneurysms 10-13.

2023年6月16日 · A mycotic aneurysm is a dangerous condition where a blood vessel wall weakens and bulges due to infection and plaque buildup. Early symptoms are often nonspecific. However, as the condition worsens, more severe symptoms such as rupture, hemorrhage, or sepsis may occur.

2023年7月10日 · A mycotic aneurysm is dilation of an arterial wall due to infection. The term "mycotic" was coined by Willaim Osler in his Gulstonian lectures, where he described a man with multiple aortic mycotic aneurysms in a patient with valve vegetations, which resembled the appearance of a fleshy fungus.

Mycotic aneurysms, though rare, are a serious medical condition that require immediate attention. These aneurysms are not caused by fungi, despite what the name might suggest. Instead, they arise due to an infection that leads to the weakening of arterial walls, resulting in an aneurysm.

Mycotic (infectious) aneurysms result from the infection of the arterial wall. The causative agent is generally a bacterium, but may also be a virus, fungus, or parasite. Mycotic aneurysm represents <5% of all intracerebral aneurysms and is potentially life threatening.

2016年3月1日 · Mycotic aneurysm (MA) is a focal dilation of an infected arterial wall. This uncommon disease follows an aggressive, unpredictable clinical course with significant mortality and presents unique diagnostic and therapeutic challenges.

2024年8月20日 · Mycotic aneurysms, characterized by vessel wall dilation resulting from infections including bacteria, fungi, and viruses, are a rare but severe consequence of systemic infections. The term 'mycotic' was coined by William Osler to describe the first instance of a fungal-induced infected aneurysm.
