“…Patient 1 died a year later due to a sudden subarachnoid hemorrhage while the 2 other patients improved or remained stable during the same length of follow-up. These results are in accordance with the reported death rates (varying from 55% at 1 year [2] to 40% at 3 years [10] in small series of patients).…”

“…F usiform cerebral aneurysms are relatively uncommon lesions compared with saccular cerebral aneurysms [1][2][3][4][5] and can be divided into 2 clinical subcategories on the basis of their clinical course. One type is acute dissecting aneurysm, which usually causes subarachnoid hemorrhage (SAH) or cerebral ischemia and more frequently involves the vertebrobasilar circulation.…”

Background and Purpose-Intracranial fusiform aneurysms can be divided into 2 clinically different subtypes: acute dissecting aneurysms and chronic fusiform or dolichoectatic aneurysms. Of these 2, the natural history and growth mechanism of chronic fusiform aneurysms remains unknown. Methods-A consecutive series of 16 patients with chronic fusiform aneurysms was studied retrospectively to clarify patient clinical and neuroradiological features. Aneurysm tissues were obtained from 8 cases and were examined to identify histological features that could correspond to the radiological findings. Results-Four histological features were found: (1) fragmentation of internal elastic lamina (IEL), (2) neoangiogenesis within the thickened intima, (3) intramural hemorrhage (IMH) and thrombus formation, and (4) repetitive intramural hemorrhages from the newly formed vessels within thrombus. IEL fragmentation was found in all cases, which suggests that this change may be one of the earliest processes of aneurysm formation. MRI or CT detected IMH, and marked contrast enhancement of the inside of the aneurysm wall (CEI) on MRI corresponded well with intimal thickening. Eight of 9 symptomatic cases but none of 7 asymptomatic cases presented with both radiological features. Conclusions-Data suggest that chronic fusiform aneurysms are progressive lesions that start with IEL fragmentation.Formation of IMH seems to be a critical event necessary for lesions to become symptomatic and progress, and this can be monitored on MRI. Knowledge of this possible mechanism of progression and corresponding MRI characteristics could help determine timing of surgical intervention. (Stroke. 2000;31:896-900.)

“…Dissecting intracranial aneurysms typically present with subarachnoid haemorrhage and have a high incidence of early rebleeding 1 whereas giant fusiform lesions present with progressive mass effect and pose less risk of haemorrhage. [2][3][4][5][6][7][8][9] Furthermore, fusiform aneurysms should be differentiated from dolichoectatic arteries in which the elongated, tortuous artery can act as a source of emboli and might therefore be best managed with antiplatelet agents or anticoagulation.…”
