BACKGROUND AND PURPOSE Carotid atherosclerosis has been associated with increased risk of stroke and poorer cognitive performance in older adults. The relation of carotid atherosclerosis to cognitive impairment and MRI indices of ischemia and aging in midlife is less clear. METHODS We studied 1975 Framingham Offspring Study participants free of stroke and dementia with available carotid ultra...

i) a case of bilateral stenosis of the internal carotid artery with aneurysm of basilar trunk is reported. 2) via femoral angiography confirmed the diagnosis which is strongly recommended in diagnosing such cases. 3) no surgica l treatment is considered. 4) no similar case has been reported in literature.

Background and Purpose—Carotid atherosclerosis has been associated with increased risk of stroke and poorer cognitive performance in older adults. The relation of carotid atherosclerosis to cognitive impairment and MRI indices of ischemia and aging in midlife is less clear. Methods—We studied 1975 Framingham Offspring Study participants free of stroke and dementia with available carotid ultraso...

A 21-year-old woman presented with an unruptured large intracavernous aneurysm, which was spontaneously revascularized via unusual collateral pathways a short time after extracranial-intracranial bypass and surgical ligation of the proximal internal carotid artery. The patient had been treated for a large basilar trunk aneurysm with intraaneurysmal embolization using Guglielmi detachable coils,...

OBJECTIVES Carotid artery pseudo-occlusion is a rare condition and its natural history and clinicopathological characteristics are not well defined. We reported our 7-year experience in the surgical treatment of carotid artery pseudo-occlusion to determine the real benefit of the surgical option. METHODS From January 2006 to December 2013, 1414 patients were treated for high-grade stenosis of...

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...

CT scan and MRI are useful for evaluating the question of cerebral infarction which may occur as a consequence of carotid artery stenosis. Infarctions related to internal carotid artery stenosis may be deep, subcortical, or cortical. However, carotid stenosis may exist in the absence of infarction on MRI and CT. The definition of asymptomatic or symptomatic carotid artery stenosis is based upon...

Splaying of carotid bifurcation on imaging, known as Lyre sign, is seen characteristically in carotid body tumors. Is positive Lyre sign always confirmatory of carotid body tumor? Here we discuss two cases of cervical sympathetic chain schwannoma. The first case presented radiologically as an enhancing lesion with splaying of external carotid artery and internal carotid artery (positive Lyre si...
