Bilateral cavernous carotid aneurysms (CCAs) are often not amenable to neurosurgical clipping or endovascular coiling. Here, we report the case of a 50-year-old female who presented with a 1-year history of gradual severe headache. Preoperative angiograms revealed bilateral CCAs. Among these findings, the right giant CCA had been trapped after the external carotid artery-saphenous vein-middle cerebral artery (ECA-SV-MCA) bypass 8 years prior. Additionally, the left CCA was again trapped after the internal maxillary artery-radial artery-middle cerebral artery (IMA-RA-MCA) bypass, followed by parent artery occlusion (PAO), because of the enlargement of a 0...

A 61-year-old woman suffered a pronounced subarachnoid hemorrhage. Conventional computed tomography angiography (CTA) showed no enhancement of the intracranial vasculature, whereas there was normal contrast enhancement of bilateral external carotid artery branches. Subsequent four-dimensional computed tomography angiography (4D-CTA) demonstrated active contrast leakage out of a ruptured basilar tip aneurysm, whereas there was no enhancement of the anterior circulation at any time point, consistent with intracranial anterior circulation arrest...

The absence of an internal carotid artery is a rare congenital anomaly. In the absence of the internal carotid artery, collateral circulations develop through the circle of Willis, persistent embryonic arteries or transcranial collaterals of the external carotid artery. Six pathways of collateral circulation have been described. Intercavernous anastomosis is between cavernous segments of the bilateral internal carotid arteries and is rarely seen. Patients with an absence of the internal carotid artery can be completely asymptomatic...

We report a case of unruptured fungal internal carotid artery (ICA) aneurysm and review the pertinent literature. A 79-year-old man presented with decreased visual acuity on the right side, and he was diagnosed with retrobulbar optic neuritis. Medical treatment with steroids resulted in Aspergillus meningoencephalitis spreading to the bottom of bilateral frontal lobes, caused by an intracranial extension of sphenoid sinusitis. Magnetic resonance imaging (MRI) performed 26 days after the start of antifungal therapy showed a denovo right ICA aneurysm projecting anteriorly into the sphenoid sinus...

True aneurysms of the external carotid artery (ECA) are extremely rare with an unknown incidence and natural history. We present the successful operative management of an asymptomatic 65-year-old man found to have bilateral internal carotid artery stenosis and bilateral ECA aneurysms. His bilateral carotid arteries were reconstructed with bifurcated interposition grafts in a staged fashion. The patient recovered without sequelae and continues to be asymptomatic 1 year after reconstruction. We present the operative management of this rare case...

AIM: The superficial temporal artery is one of the main terminal branches of the external carotid artery. This artery ascends through the lateralposterior margin of the zygomatic arch to reach the temporal region of the scalp. The superficial temporal artery divides its frontal and parietal branches around the zygomatic arch. MATERIAL AND METHODS: The raw data of the Three-dimensional Computerized Tomography Angiography (3D-CTA) were transferred to computer and recorded in a software program...

We present the first report, to our knowledge, in which revascularization of the middle cerebral artery (MCA) with a high flow extracranial-intracranial procedure resulted in symptomatic hyperemia of the posterior circulation. Cerebral hyperperfusion syndrome (CHS) is a poorly understood phenomenon that is classically seen in the distribution of a revascularized artery. A 37-year-old woman presented with a 3 month history of cognitive and speech difficulties, persistent headaches, weakness, numbness, and paresthesia which was worse in the right extremities and face...

INTRODUCTION: Intracranial placement of flow-diverter (FD) stents provides a safe and effective treatment for aneurysms.(1) However, long-term angiographic follow-up is indicated, since in-stent stenosis and late thrombosis as a consequence of poor vessel wall apposition increase the risks of stroke-related complications.(1,2) In addition to conventional angiography, high-resolution contrast-enhanced cone-beam CT (VasoCT) may provide improved three-dimensional visualization of stent deployment and apposition...

A 44-year-old woman presented with recurrent episodes of thunderclap headache. Neurological examination and computed tomography brain imaging were unremarkable. Cerebrospinal fluid findings were consistent with subarachnoid hemorrhage. Computed tomography angiography of the circle of Willis showed multiple areas of segmental vasoconstriction. This finding was confirmed on cerebral catheter angiography, with segmental vasoconstriction involving bilateral internal carotid, posterior cerebral, and external carotid branches...

The aim of this study was to analyze clinical and neuroimaging manifestations of vertebral artery (VA) dissection. Twenty seven patients (19 men, 8 women, mean age 34.1±6.1) with the VA dissection were enrolled. All the patients underwent MRA, neck MRI (T1 f-s, T2 f-s) and head MRI. Twenty six of 27 patients had follow-up MRA/MRT studies: during the acute period and after 2 months or later. Clinical manifestations of VA dissection included ischemic stroke (IS, 52%), transient ischemic attack (TIA, 4%) and isolated neck pain/headache (44%)...

The majority of episodes of spontaneous posterior epistaxis treated with embolisation are idiopathic in nature. The angiographic findings are typically normal. Specific angiographic signs are rare and may include the following: a tumour blush, telangiectasia, aneurysm, and/or extravasation. Selective internal carotid artery (ICA) angiography may show rare causes of epistaxis, such as traumatic or mycotic aneurysms, which require different treatment approaches. Complete bilateral selective external and internal carotid angiograms are essential to evaluation...

OBJECTIVE: Although it is hypothesized that inflammatory signals and/or hemodynamic stress resulting from carotid disease increase the risk of aneurysm formation and growth, a relationship between intracranial aneurysms and extracranial carotid artery disease (ECAD) has not been explored. Here, we examined the characteristics of intracranial aneurysms associated with ECAD. METHODS: A total of 606 consecutive patients with stenosis of 50% or more of the proximal internal carotid artery (pICA) were enrolled...

The aneurysmal bone cyst (ABC) is a benign cystic and expanding osteolytic lesion consisting of bone-filled spaces of variable size, separated by connective tissue containing trabeculae of bone or osteoid tissue and osteoclast giant cells. Radiographic findings may vary from unicystic or moth-eaten radiolucencies to extensive multilocular lesions with bilateral expansion and destruction of mandibular cortices. Treatment modalities include curettage (with reported recurrences) and resection with immediate reconstruction...

BACKGROUND: The treatment of unclippable vertebral artery (VA) aneurysms incorporating the posterior inferior cerebellar artery with parent artery preservation is among one of the most formidable challenges for cerebrovascular microsurgery and endovascular surgery. We propose that intracranial VA reconstruction using an extracranial VA-to-intracranial VA (VA-VA) bypass with a radial artery graft or an occipital artery graft may be an additional technique in the armamentarium to treat these formidable lesions...

Cervicocephalic fibromuscular dysplasia (FMD) is an idiopathic, non-inflammatory and non-atherosclerotic arteriopathy which usually affects small- and medium-sized cervical arteries distributed at the atlas and axis interspace. Few cervicocephalic FMD patients are associated with multiple intracranial aneurysms which may rupture or develop. So the authors describe a cervicocephalic FMD patient with a history of right oculomotor palsy in 2000. Angiography revealed bilateral internal carotid artery (ICA) aneurysms and a fusiform aneurysm in right vertebral artery...
