This paper describes a case of intracerebral hiemorrhage due to rupture ofa congenital aneurysm situated on the right anterior cerebral artery. After a series of acute cerebral vascular incidents the clinical picture was that produced by a rapidly expanding frontal lesion. After full investigation, including air encephalography, the diagnosis of ruptured anterior cerebral aneurysm was made and ...

A case of agenesis of the internal carotid artery (ICA) associated with an anomalous middle cerebral artery (MCA) originating from the contralateral ICA is herein reported. This rare case presented with a subarachnoid hemorrhage (SAH) due to a rupture of an anterior communicating artery (ACoA) aneurysm.

Aneurysms of the anterior communicating artery are formidable lesions even when successfully treated surgically for they may produce long-standing ill effects that are out of proportion to the size of the lesion. Indeed, some of our operations which we have judged to be excellent from a technical standpoint have proved to be most disappointing as these patients may develop persistent mental and...

Although variations of the anterior cerebral artery (ACA)-anterior communicating artery complex are commonly identified on imaging studies, an infraoptic course of the ACA is exceedingly rare. What is believed to be the first case of an infraoptic course of the ACA discovered with MR angiography and further characterized with conventional angiography is presented. The high prevalence of associa...

A case with infarction in the territory of the anterior choroidal artery (AChA) due to embolic occlusion of the internal carotid artery (ICA) is rare. We described two cases and investigated the mechanism of the territory of the AChA. Case 1 was a 69-year-old man. Case 2 was a 71-year-old woman. The neurological examination in both cases showed left homonymous hemianopsia, left facial palsy, le...

BACKGROUND AND PURPOSE In some patients with nonperimesencephalic nontraumatic subarachnoid hemorrhage (aneurysmal SAH), no aneurysm can be found on digital subtraction angiography (DSA), and repeat DSA is advocated. 3D rotational angiography (3DRA) is considered superior to DSA in the detection of small intracranial aneurysms. In this study, we assessed the additional diagnostic value of 3DRA ...

Headache can be attributed to cranial or cervical vascular disorders including ischemic stroke or transient ischemic attack, non-traumatic intracranial hemorrhage, unruptured vascular malformation, arteritis, carotid-vertebral artery pain, and cerebral venous thrombosis. Here, we present a case report of unruptured saccular aneurysm with migraine. The patient was a previously healthy 32-year-ol...
