Classification of intracranial aneurysms may be based on morphology, size, location and etiology. The majority of intracranial aneurysms are true aneurysms containing all layers or components of the normal vessel wall. In contrast, in false aneurysms or pseudoaneurysms, the vascular lumen does not enlarge, although the external diameter of the abnormal segment may be increased. These aneurysms are rare within the skull. 

Although the pathogenesis and etiology of cerebral aneurysms has been studied extensively, both are... 

Mycotic aneurysms from bacterial endocarditis were initially the most common cause of hepatic artery aneurysm [11]. However, traumatic and iatrogenic causes are likely the most common etiology today. Medial degeneration and atherosclerotic changes have also been implicated. However, atherosclerosis is more likely the result rather than the cause of the... 

The superior mesenteric artery aneurysm is the third most common VAA but only accounts for 6% of all splanchnic aneurysms. It is typically associated with an infectious etiology such as endocarditis. Thrombosis and dissection can be seen with these lesions and patients can present with symptoms of mesen-...
