PMID: 7057305 A berry aneurysm, which looks like a berry on a narrow stem, is the most common type of brain aneurysm. Before a larger aneurysm ruptures, the individual may experience such symptoms as a sudden and unusually severe headache, nausea, vision impairment, vomiting, and loss of consciousness, or no symptoms at all.[6].

An intracranial aneurysm, also known as a brain aneurysm, is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel. Ann Rheum Dis 28: 246–251, 1969, Grode ML, Saunders M, Carton CA: Subarachnoid hemorrhage secondary to ruptured aneurysms in infants. The most common type of cerebral aneurysm is called a saccular, or berry, aneurysm, occurring in 90 percent of cerebral aneurysms. [10][citation needed], A ruptured microaneurysm may cause an intracerebral hemorrhage, presenting as a focal neurological deficit. Meanwhile, aneurysms less than 7 mm arise from the anterior and posterior communicating artery and are more easily ruptured when compared to aneurysms arising from other locations. [9] In addition, some parts of the brain vasculature are inherently weak—particularly areas along the circle of Willis, where small communicating vessels link the main cerebral vessels. Here we review the current understanding of the genetic architecture of intracranial berry aneurysms (IBA) to aid in the genetic counseling of patients at risk for this condition. Q J Exp Physiol 60: 181–192, 1975, Stehbens WE: Ultrastructure of aneurysms. Analysis of data from this trial has indicated a 7% lower eight-year mortality rate with coiling,[23] a high rate of aneurysm recurrence in aneurysms treated with coiling—from 28.6–33.6% within a year,[24][25] a 6.9 times greater rate of late retreatment for coiled aneurysms,[26] and a rate of rebleeding 8 times higher than surgically-clipped aneurysms. Natural history of subarachnoid hemorrhage, intracranial aneurysms, and arteriovenous malformations. Multiple aneurysms are seen in about 20-30% of cases of berry aneurysm.
