An 85-year-old man complained of a 2-month history of pain on the left side of his face. Brain computed tomography (CT) and magnetic resonance imaging/magnetic resonance angiography did not clearly show any intracranial abnormality and only showed fluid effusion in his left sphenoid sinus. Filamentous fungi were detected from the left sphenoid sinus specimen. The isolate was Scedosporium apiosp...

A 65‐year‐old man with a history of smoking for 30 years was hospitalized in our stroke unit with a complaint of recurrent transient right‐side numbness. Brain magnetic resonance imaging (MRI)/magnetic resonance angiography did not demonstrate any abnormities. However, he experienced another two same episodes before discharge. Further, head and neck computed tomography angiography (CTA) showed ...

INTRODUCTION Carotico cavernous sinus fistula (CCF) is an abnormal communication between the carotid artery and the cavernous sinus and is classified angiographically as dural or direct. Spontaneous CCF is a dural arterio-venous fistula at the cavernous sinus which is different from traumatic CCF or CCF associated with a ruptured aneurysm at the cavernous internal carotid artery. Cerebral angio...

We have worked on the measurement protocol and related image reconstruction of 4D data sets in the field of time-resolved Contrast-Enhanced Magnetic Resonance Angiography (CE-MRA). The method aims at improving the interpolation of sparsely sampled -space data. It is based on exploiting prior knowledge on the time courses (TCs) of the image pixels, when monitoring the uptake of contrast agents i...

Recognition by Contrast-Enhanced, Three-Dimensional Magnetic Resonance Angiography To the Editor: The magnetic resonance angiogram of the left hand shown by Wiesmann et al1 is an incomplete display of the arteries that is further confounded by venous contamination. From this image, one cannot conclude that “there is no evidence of vasculitis or arterial stenosis or occlusion.” Spatial resolutio...

Copyright © 2007 Massachusetts Medical Society. A 51-year-old woman presents with a generalized tonic–clonic seizure. After a brief postictal period, she recovers fully and does not report headache or other neurologic symptoms. She takes no medications and her medical history is unremarkable. Computed tomography of the head suggests a right occipital arteriovenous malformation, without evidence...

Transient cortical blindness after coronary angiography and bypass graft is a very rare complication. In this report we present the case of a 63-year-old man who developed transient cortical blindness within 30 minutes of coronary angioplasty and graft study, but subsequently recovered within 72 hours without any neurological deficit. A plain computed tomography brain scan showed bilateral symm...

The diagnosis of intracranial stenosis has improved with the advent and availability of non-invasive vascular imaging tests. Vascular imaging modalities to consider include transcranial Doppler, magnetic resonance and computed tomographic angiography. While these have strengths and weaknesses, they provide anatomic information. Physiologic and/or hemodynamic data can be gleaned from perfusion i...

BACKGROUND AND PURPOSE Intracranial arterial steno-occlusive disease is prevalent among non-white populations. We explored whether a similar pattern exists in Egyptians and assessed its clinical-radiological associations. METHODS Consecutive acute ischemic stroke patients were recruited for 6 months and had magnetic resonance imaging/magnetic resonance angiography of brain within 2 days of th...

BACKGROUND Giant cell arteritis typically involves the temporal arteries, but can involve other cranial arteries. Temporal artery biopsy is the mainstay for the diagnosis of giant cell arteritis; however, biopsy may be problematic if giant cell arteritis involves other cranial arteries that are inaccessible for sampling. In these situations, magnetic resonance angiography is a useful, non-invas...
