PURPOSE To assess the prevalence of MR evidence for diffuse axonal injury at 1.5 T in patients with normal head CT findings after mild head injury. METHODS Twenty consecutive patients with mild head injury (Glasgow Coma Scale, 13 to 15; no subsequent deterioration, loss of consciousness < 20 minutes) and normal head CT findings were examined with MR at(More)
SUMMARY A 73-year-old man was admitted with invasive aspergillus of the sphenoid sinus. Endoscopic debridement of the sphenoid sinus was complicated by rupture of a mycotic cavernous carotid artery aneurysm with severe epistaxis. The aneurysm was closed emergently by endovascular coil placement. Subsequently, the mycotic aneurysm extended intradurally and(More)
BACKGROUND AND PURPOSE To explore relationships among gender, body size, neck size, and the diameters of the common carotid artery (CCA) and internal carotid artery (ICA). METHODS Using multivariate regression, the best predictors of sonographic diameters of CCA and ICA were determined based on age, height, weight, body mass index, body surface area, neck(More)
PURPOSE To assess magnetic resonance (MR) angiography for the detection and characterization of angiographically proved intracranial aneurysms by using an advanced method of postprocessing, in a blinded-reader study. MATERIALS AND METHODS One hundred fifty-eight vessels were examined with catheter angiography and three-dimensional time-of-flight MR(More)
OBJECTIVE To identify clinical and angiographic factors of cerebral arteriovenous malformations (AVMs) associated with hemorrhage to improve the estimation of the risks and help guide management in clinical decision making. METHODS We conducted a retrospective analysis of 100 consecutive adults who have presented during the past 3 years to our institution(More)
Recently, the benign nature of aneurysms of the cavernous carotid artery has been questioned. In a review of cases evaluated from 1980 to 1990 with this developmental aneurysm, the authors found 70 patients with 79 cavernous carotid artery aneurysms. As expected, the great majority (59 patients) had ophthalmoplegia as the initial problem. Retro-orbital pain(More)
PURPOSE Dural arteriovenous fistulas (DAVFs) are acquired arteriovenous shunts located within the dura. The highly variable natural history and symptomatology of DAVFs range from subjective bruit to intracranial hemorrhage and are related to the lesion's pattern of venous drainage and its effect on the drainage of adjacent brain. We examined the prevalence(More)
OBJECTIVE Pediatric cerebral aneurysms are rare. There are very few recent studies that focus on the multidisciplinary treatment of ruptured aneurysms. We reviewed our pediatric endovascular and surgical experience with ruptured cerebral aneurysms. METHODS Pediatric patients aged 16 years and younger who were admitted with a diagnosis of aneurysmal(More)
Carotid endarterectomy is increasingly used to decrease the risk of stroke associated with cervical atherosclerotic stenosis, and some investigators claim that the results and benefits for carotid stenting are comparable with those of endarterectomy. A review of the literature reveals that there is incomplete knowledge concerning carotid artery(More)
