With the rapid development of computer technology and the successful Application of medical imaging, computer aided diagnosis technology develops increasingly. On the basis of the research and analysis of cerebral aneurysm and DSA imaging mechanism, this paper proposed a cerebral aneurysm recognition method using Bayesian classification. After cerebral vessel image is preprocessed, geometrical ...

Arterial bifurcations in the circle of Willis were observed three-dimensionally in 44 cases of cerebral aneurysm and 45 control cases. Variations of the circle of Willis were also studied in relation to cerebral aneurysm. The following results were obtained : 1. Aneurysm always occurred at the apex of the cerebral arterial bifurcation where axial flow in the parent artery immediately proximal t...

Hemodynamic parameters of cerebral aneurysm play an important role in the progression, growth and rupture of an aneurysm. Therefore, the knowledge of hemodynamic parameters may provide physicians with understanding of aneurysm initiation, growth and rupture. Progression of medical imaging technology and improvement of the computer has enabled to predict the hemodynamics of aneurysm with increas...

Introduction: The present case study reports an intraparenchymal hemorrhage from a ruptured basilar tip aneurysm without subarachnoid hemorrhage. Case Report: A 57-year-old male presented with intraparenchymal hemorrhage from a ruptured basilar tip aneurysm without subarachnoid hemorrhage. The patient had successful endovascular embolization of his ruptured cerebral aneurysm 9 years previously....

Cases of spontaneous regression of cerebral aneurysm remnant after incomplete surgical clipping have been rarely reported. This paper reports the regression of an aneurysm remnant after incomplete surgical clipping during postsurgical follow-up. A 50-year-old male presented with subarachnoid hemorrhage because of rupture of an anterior communicating artery aneurysm. An emergency clipping of the...

BACKGROUND Whether unilateral moyamoya disease (MMD), confirmed by steno-occlusive lesion at the terminal portion of internal carotid artery with formation of moyamoya vessels unilaterally and normal or equivocal findings contralaterally, is an early form of definite (bilateral) MMD remains controversial. It is well-known that adult patients with MMD tend to suffer from cerebral hemorrhage, occ...

Seizures as a presenting feature of unruptured cerebral aneurysm are unusual. We report two cases of unruptured cerebral aneurysm presented with seizures. In both cases the seizures controlled following surgical ablation of the aneurysm.

RATIONALE There were a few case reports concerning epidermoid tumor coexisted with multiple cerebral aneurysms. Here, we present one case of coexistence of intracranial epidermoid tumor and multiple cerebral aneurysms and performed a literature review. PATIENT CONCERNS A 42 years old male patient was admitted to our institution with complaints of headache and dizziness. INTERVENTIONS The ra...
