A duplicated middle cerebral artery (DMCA) aneurysm is characterized by the presence of an aneurysm at the bifurcation of the original and duplicated middle cerebral arteries. The authors reported a very rare case that had a DMCA aneurysm and underwent multimodality treatment. The patient was 49-year-old male and presented with headache. His examinations revealed an aneurysm at the origin of th...

Surgical intervention is a gold standard technique for ruptured and unruptured middle cerebral artery bifurcation aneurysm. Before surgical intervention it is necessary to know the three-dimensional shape, surgical position, projection and position of the aneurysm and the course of the parent artery. In a demonstrative case with middle cerebral artery aneurysm, using the OsiriX MD image process...

BACKGROUND Brain tumours that are associated with cerebral aneurysms are rare occurrences, whereas the coexistence of brain tumours and intra-tumoural aneurysms is even rarer. There have been 12 brain tumour cases that have been reported in the literature that describe an aneurysm within a brain tumour, with 4 of these tumours being meningiomas. CASE DESCRIPTION A 34-year-old male patient pre...

BACKGROUND Cerebral saccular aneurysm is a major cause of subarachnoid hemorrhage, one of the cerebrovascular diseases with the highest mortality. The mechanisms underlying the development of aneurysms, however, still remain unclear. We have made a series of reports on an animal model of experimentally induced cerebral aneurysms that resemble human cerebral aneurysms in their location and morph...

PURPOSE An accurate determination of the natural history of a cerebral aneurysm has implications on management. Few risk factors other than female gender and cigarette smoking have been identified to be associated with cerebral aneurysm progression, particularly rapid progression. MATERIALS AND METHODS This case series and literature review serves to illustrate a relationship between spontane...

Simultaneous occurrence of carotid atherosclerotic disease and ipsilateral cerebral aneurysm is known because of common risk factors. When interventional neuroradiologists encounter such cases, issue of 'in which order to treat these lesions ' is raised. If carotid artery disease is treated first, then acute increase in perfusion pressure and high dose antiplatelets might increase the risk of a...

OBJECTIVE Ruptured middle cerebral artery (MCA) aneurysm with intrasylvian hematoma usually accompanied by progressive cerebral swelling with poorer outcomes. The authors present characteristics and importance of intrasylvian hematoma removal in the aneurysm surgery. MATERIALS AND METHODS From 2012 February to 2014 March, 24 aneurysm surgeries for ruptured MCA aneurysms with intrasylvian hema...

Cerebral aneurysms are well known to be associated with cardiac myxomas. The mechanism of cerebral aneurysm formation remains to be elucidated. Embolization of tumor particles in the vessel wall has been proposed as the likely mechanism for aneurysm formation. Recent reports suggest interleukin-6 (IL-6) may play a role as well. We describe a patient who presented with subarachnoid hemorrhage se...

AIM The brain venous drainage dominance is generally divided into three groups; right or left dominance and co-dominance. There is no study in the literature examining the link between brain venous drainage and aneurysm formation or rupture. Our aim was to evaluate the association between venous dominancy, aneurysm formation and rupture. MATERIAL AND METHODS Eighty-six patients, who underwent...

The progression of a cerebral aneurysm involves degenerative arterial wall remodeling. Various hemodynamic parameters are suspected to be major mechanical factors related to the genesis and progression of vascular diseases. Flow alterations caused by the insertion of coils and stents for interventional aneurysm treatment may affect the aneurysm embolization process. Therefore, knowledge of hemo...
