Distal anterior cerebral artery aneurysms are infrequent. The most common location is at the bifurcation of the pericallosal and callosomarginal arteries. Cerebral artery anomalies can sometimes, at least partially, explain aneurysm formation in less common locations in relation to hemodynamic stress caused on the vascular wall. We report a very rare case of subarachnoid hemorrhage due to a rup...

We report what may be the first case of lipoma of the corpus callosum associated with a distal anterior cerebral artery saccular aneurysm. The pathogenetic correlation between the callosal lipoma and the distal anterior cerebral artery saccular aneurysm is discussed.

Fenestration of the anterior cerebral artery is rare. The authors describe a case of an aneurysm arising from the proximal end of a fenestration of the anterior cerebral artery demonstrated by angiography.

In an anatomic study of 374 autopsied brains, Crompton and Lond (1) found that in 3% (10 of 374 cases) there was an artery arising from the internal carotid artery between its terminal bifurcation and the origin of the anterior choroidal artery, which passed into the Sylvian fissure along with the ordinary middle cerebral artery. He termed this vessel an accessory middle cerebral artery. In add...

Course and distribution information on arteries in the rat rhinencephalon was not found in the literature. Such data are useful for designing experiments and interpreting findings, tracing nerve fibers on or to intracerebral vessels, and in considering routes for diffusion or transport of intracerebral injected agents. Adult rats were perfused with silicone rubber and many brains were cleared i...

mechanical thrombectomy has shown promising results in large vessel ischemic stroke, with recent large trials changing to guidelines worldwide. in this presentation, results from the five recent randomized trials will be discussed. there is an ongoing debate on the inclusion and exclusion criteria of mechanical thrombectomy. it can be done in large vessel occlusions, including up to m2 middle c...

A previously healthy 15-month-old girl became pale and lethargic. CT showed subarachnoid hemorrhage. Cerebral angiography showed a 5-mm aneurysm in the M1 segment of the left middle cerebral artery (Fig. 1 A). The anterior cerebral artery was not visualized on the left carotid artery angiogram. Both anterior cerebral arteries filled from the right carotid injection. An additional vessel origina...

Anatomy of the Middle Cerebral Artery: The Temporal Branches • Nineteen out of 23 middle cerebral arterial specimens had as the first major branch of the middle cerebral artery a sizable anterior temporal artery; a trunk forming the anterior and middle temporal branches; a trunk forming the anterior, middle, and posterior temporal arteries; or a trunk forming temporal and angular arterial branc...

Ipsilateral motor or sensory symptoms associated with carotid occlusive diseases are rare. We report a 52-year-old man who presented with aphasia, right hemiparesis, mild left leg weakness, and bilateral Babinski's signs. During the previous 10 days, he had experienced three episodes of left leg numbness and incoordination that occurred either alone or in association with right arm and leg weak...

The growing dependence on electricity in our daily lives has increased the incidence of electrocution injuries. Although several neurological injuries have been described previously, acute stroke due to electrocution is rare. Our patient, a previously healthy man, was electrocuted after he grabbed a "live" high-voltage wire. Although he was hemodynamically stable, he remained confused with lang...
