Basilar artery herniation into the sphenoid sinus resulting in pontine and cerebellar infarction: demonstration by three-dimensional time-of-flight MR angiography.
نویسندگان
چکیده
We report a unique case of basilar artery herniation into the sphenoid sinus caused by a traumatic skull base fracture, with persistent patency of the basilar artery. Clinical and imaging features, as well as the relevant literature, are described.

Cerebral fungal infection with mycotic aneurysm of basilar artery and subarachnoid haemorrhage.
A 28-year-old Pakistani man was admitted with unresolved severe headaches for the past four weeks. Magnetic resonance (MR) imaging and MR angiography showed an enhancing mass in the sphenoid sinus, bilateral cerebellar infarcts and aneurysmal dilatation of the basilar artery. The differential diagnosis included fungal infection versus neoplastic lesion. The scrappings taken through the endoscop...
متن کاملBasilar artery atherosclerotic plaques in paramedian and lacunar pontine infarctions: a high-resolution MRI study.
BACKGROUND AND PURPOSE Pontine infarction is most often related to basilar artery atherosclerosis when the lesion abuts on the basal surface (paramedian pontine infarction), whereas small medial pontine lesion is usually attributed to small vessel lipohyalinosis. A previous study has found that high-resolution MRI can detect basilar atherosclerotic plaques in up to 70% of patient with paramedia...
متن کاملBithalamic hyperintensity on T2-weighted MR: vascular causes and evaluation with MR angiography.
PURPOSE To determine whether MR angiography can be used to differentiate between the two vascular causes of bithalamic hyperintensity on T2-weighted MR images: "top of the basilar" artery occlusion and deep cerebral vein thrombosis. METHODS A retrospective review identified six patients with bithalamic T2 hyperintensity of vascular causes. MR angiography was performed in four patients, MR ang...
متن کامل3DFT MR angiography of carotid and basilar arteries.
Three-dimensional Fourier transform (3DFT) time-of-flight and two-dimensional Fourier transform (2DFT) projection phase-contrast MR angiography was performed in eight healthy volunteers and in 14 patients with known carotid artery or basilar artery occlusion, stenosis, or dissection. Comparative angiography was available in 13 cases (although in some cases the studies were separated by a number...
متن کاملParallel and spiral flow patterns of vertebral artery contributions to the basilar artery.
PURPOSE To demonstrate that the in vivo flow from individual vertebral arteries can be imaged and tracked in the basilar artery by use of saturation planes with three-dimensional time of flight MR angiography. METHODS Twenty volunteers were studied with intracranial three-dimensional time of flight angiography MR. The MR angiography was repeated with saturation of the individual vertebral art...
