OBJECTIVES Bilateral carotid artery occlusion associated with lymphocytic hypophysitis is exceedingly rare. We describe this association and review the literature. METHODS The authors describe a 38-year-old woman with a history of severe headaches. Magnetic resonance (MR) imaging showed an intrasellar mass with invasion of both cavernous sinuses. Lymphocytic hypophysitis was diagnosed by tran...
In patients with high-grade atherosclerotic stenosis or occlusion of the extracranial cerebral arteries, subarachnoid hemorrhage (SAH) may occur, potentially due to rupture of fragile dilated pial collateral vessels. This association has been well described in Moyamoya disease. There are only few cases in the literature that reported SAH due to bilateral carotid artery stenosis but intraventric...
A 43-year-old woman suffered a blast-type injury to the head and neck. She subsequently developed bilateral internal carotid artery occlusion and bilateral anterior cerebral artery infarction not demonstrated by magnetic resonance imaging scan 24 hours after the explosion, but confirmed by a second scan 8 days after the explosion. In patients with blast-type injury to the head and neck who deve...
Spontaneous bilateral cerebellar infarction in the territory of the superior cerebellar arteries is extremely rare. Occasionally there have been reports of bilateral cerebellar infarction due to vertebrobasilar atherosclerotic occlusion or stenosis, whereas no report of bilateral cerebellar infarction due to complicated hemodynamic changes. In this report, we present a patient with bilateral ce...
Background and Objective: Numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. One physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. In this study, we can predict hemodynamic behavior of one artery of circulatory system (...
In patients with cerebral ischemia, both during hospitalization and in the community, the prevalence of major depression is evident. Since the depression has a negative impact on recovery, its timely diagnosis and treatment is essential. This study aimed to evaluate the effect of the oral administration of Chevilan extract (Ferulago angulata hydroalcoholic extract; 100, 200 and 400 mg/kg) on br...
Background: Knowledge of variations in the origin of vertebral artery (VA) is indispensable to vascular surgeons. Aberrant origin of vertebral artery on either side is an uncommon finding. There are unilateral and bilateral variability in VA origin. Case presentation: We present a case of vertebral artery dissection who was found to have bilateral VAs aberrant origin. The right VA took origin ...
