Fusiform aneurysms of cerebral arteries are less prevalent than saccular aneurysms and are rarely associated with subarachnoid hemorrhage (SAH). In this article, we report SAH due to a rare case of bilateral fusiform aneurysm of the supraclinoid segment of the internal carotid arteries (ICAs) (C4 segment of the ICA).

<i>Multiple fusiform aneurysms occurring in a single patient are very uncommon. Fusiform aneurysms affecting the anterior circulation are extremely rare and reported cases involve the middle cerebral artery and internal carotid artery. We report here a case of a 55-year-old African American male who had a history of multiple strokes and who was found unresponsive prior to his latest hospital admission. Neuroimaging was remarkable for multiple fusiform aneurysms involving segments of the anterior, middle and posterior cerebral arteries as well as subarachnoid and intraparenchymal hemorrhage...

Congenital agenesis of the internal carotid artery is a very rare anomaly. Intracranial circulation in the involved internal carotid artery territory is maintained by collateral circulation from the contralateral internal carotid artery through the anterior communicating artery and from the vertebrobasilar system through the posterior communicating artery. Usually, patients with internal carotid artery agenesis are asymptomatic due to collateral circulation, but they may present with headache, seizures, or transient ischemic attack...

Ophthalmic artery aneurysms account for 5% of all cerebral aneurysms and are an important cause of morbidity and mortality related to subarachnoid hemorrhage. The diagnosis is often made only when the aneurysm is large enough to become symptomatic. They remain technically challenging for both neurosurgeon and interventional radiologist. We present the case of a 62-year-old woman admitted for transient loss of consciousness, followed by generalized tonic-clonic seizures. Computed tomography (CT) showed a subarachnoid hemorrhage (SAH), clinically graded as Hunt and Hess III...

The Pipeline Embolization Device™ (PED; Covidien Neurovascular Inc, Irvine, CA, USA) is a flow-diverting stent often used for the endovascular treatment of large or giant, wide-necked intracranial aneurysms of the internal carotid artery. Because of the inherent thrombogenicity of intracranial stents, dual-antiplatelet therapy is initiated after placement, which has been shown to decrease morbidity and mortality related to perioperative ischemic events in neurointerventional procedures. However, in some series, as much as 50% of patients demonstrate clopidogrel non-responsiveness...

BACKGROUND: Aberrant internal carotid artery (aICA) is an anatomical anomaly whereby the internal carotid artery (ICA) courses through the tympanic cavity without separation by bone. Since aICA is rare, there are no definite treatment strategies for aICA and its complications. CASE DESCRIPTION: We report a case of aICA accompanied by pseudoaneurysm formation and massive bleeding. Our case was a 31-year-old woman with a 2-year history of hearing loss, ear fullness, and pulsatile tinnitus in her left ear...

We describe a case of acute oculomotor nerve palsy caused by a ruptured middle cerebral artery (MCA) aneurysm. A 59-year-old female presenting with headache and nausea was admitted to our hospital. Her consciousness was alert, and had no other neurological deficit without left oculomotor nerve palsy. A computed tomography (CT) showed SAH extending from left sylvian cistern to basal cistern. CT angiography revealed a left MCA aneurysm which protruded toward internal carotid artery. The patient was successfully treated with surgical clipping...

BACKGROUND: Full visualization of the aneurysm neck is usually impossible in a classical pterional craniotomy when a paraclinoid aneurysm is located on the opposite side of the internal carotid artery (ICA). Optic nerve (ON) retraction is required for better aneurysmal exposure, but ON injuries may occur. CLINICAL DESCRIPTION: In a case of a 70-year-old female harboring a carotid cave aneurysm, we introduced a new method to delineate better the margins of the aneurysm neck by utilizing intraoperative three-dimensional (3D) rotational angiography (RA) with dual-volume reconstruction...

Recently developed flow diverters, such as the pipeline embolization device (PED), allow for safe and efficacious treatment of giant intracranial aneurysms, with high occlusion rates and a low incidence of complications. However, incomplete obliteration after PED treatment may lead to aneurysm regrowth and delayed rupture. Herein, we report a case of a partially thrombosed giant aneurysm of the cavernous internal carotid artery that showed progressive recanalization at 1-3 months after application of a PED...
