BACKGROUND Bacterial meningitis complicated by thrombosis, vasculitis, and aneurysm formation affecting both small and distal branches of cerebral vessels has been well described. Involvement of major cerebral vessels is rare and has only been documented late in the course of disease. CASE DESCRIPTION We describe the clinical and pathological findings in a young man who presented with pontine...

Aneurysmal subarachnoid hemorrhage (SAH) is one of the most severe forms of stroke, which results from the rupture of a cerebral aneurysm. SAH is the only type of stroke with a female predominance, suggesting that reproductive factors may play a significant role in the etiology. Estrogen has important effects on vascular physiology and pathophysiology of cerebral aneurysm and SAH and, thus, pot...

A previously healthy 9-year-old girl presented with sudden-onset headache followed by confusion. In the emergency department, she was hypertensive, bradycardic, and no longer responsive to any stimuli. An emergent head CT scan demonstrated a left frontal intraparenchymal hematoma with intraventricular and subarachnoid extension as well as subfalcine herniation (figure). She underwent decompress...

The aim of this study was to investigate the feasibility of the simultaneous clipping of bilateral middle cerebral artery aneurysms via the unilateral pterional approach in Asian patients. The study included 10 cases of bilateral middle cerebral artery aneurysms, including two males and eight females; the ratio of male to female patients was 1:4. The patients ranged in age from 44 to 67 years o...

Background Cerebral artery vasospasm accounts for the majority of delayed neurological deficits in ruptured aneurysm patients. We report two cases and review the literature* of patients who developed symptomatic vasospasm after treatment for unruptured cerebral artery aneurysms with clip ligation. Preand post-operative imaging and studies revealed absence of subarachnoid or focal hemorrhage. Ca...

We herein report the first case of progressive perianeurysmal edema preceding the rupture of a small saccular aneurysm, without any intervention or intraluminal thrombosis. A 71-year-old woman was incidentally noted to have a cerebral aneurysm (5mm in diameter) at the lower basilar artery. Twelve months later, magnetic resonance (MR) imaging showed a T2-elongated area around a dome of the aneur...

The anaesthetist may be involved at various stages in the management of subarachnoid haemorrhage (SAH). Thus, familiarity with epidemiological, pathophysiological, diagnostic, and therapeutic issues is as important as detailed knowledge of the optimal intraoperative anaesthetic management. As the prognosis of SAH remains poor, prompt diagnosis and appropriate treatment are essential, because ea...

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...

Distal middle cerebral artery aneurysm is rare and can develop from trauma, infection, atherosclerosis, or surgery. Nasogastric (NG) tube insertion is a common and safe procedure for stroke patients with dysphagia. In this case, the patient showed right internal border-zone infarction without major arterial occlusion. Magnetic resonance angiography of the brain showed no intracranial aneurysm. ...
