We report a case of symptomatic symmetrical, bilateral absence of the cavernous internal carotid (ICA) and transdural vertebral artery (VA) segments with formation of a rete mirabile. There have been similar reports in Asian patients; ours is the first in the Western population. A 29- year-old woman presented with recurrent temporary blindness and an(More)
BACKGROUND AND PURPOSE The dural sinus occlusion has been shown to be effective in the treatment of some dural arteriovenous shunts (DAVS). No long-term results are available, however, regarding the significance of occlusion of a dural sinus. If the disease will stop or if other events will occur later in the remaining sinuses are not well known yet.(More)
BACKGROUND The association between the ankle brachial index (ABI) and the measurement of intimal medial thickness (IMT) has not been fully studied. OBJECTIVE We aimed to evaluate whether the prevalence of carotid atherosclerosis was higher in patients with ABI < 0.9 than in those with ABI > 0.9. METHODS From January 2011 to December 2011, 118 patients(More)
I read with great interest the article by Dehdashti et al. [1], in which they describe a very interesting occurrence of an ophthalmic artery (OA) aneurysm in the context of multiple aneurysms, and discuss the anatomical features. They mentioned that the aneurysm was ‘‘lying on the first bifurcation of the intraorbital ophthalmic artery’’. ‘‘Bifurcation’’(More)
We report a rare case of craniofacial arteriovenous metameric syndrome (CAMS) 3 arteriovenous malformations of the mandible, left VIII nerve and petrous bone. The patient, a 19-year-old girl, presented with profuse gingival bleeding during a dental procedure and we diagnosed CAMS 3 during a pre-embolisation angiogram. The distribution of the vascular(More)
In the present study we describe the cases of two patients with cluster-like headache related to intracranial carotid artery aneurysm. One of these patients responded to verapamil prescription with headache resolution. In both cases the surgical clipping of the aneurysm resolved the cluster pain. These findings strongly suggest a pathophysiological link(More)
p a ngiodyplastic lesions of the face are classified as ascular tumors or vascular malformations, each ategory having distinct etiologies and clinical preentations. Hemangiomas are vascular tumors that xhibit endothelial hyperplasia, which increases hrough rapid mitotic cellular proliferation. Vascular malformations (VMs) exhibit a normal umber of(More)
Methods Data of 100 cerebral angiographies were retrospectively analyzed (p = 0.05). Results Mean age was 56.3 years, 62% female and 38% male. Measurements and dominance are shown in the Tables. There was no association between age or gender and dominance. Right parasagittal division of the superior sagittal sinus was associated with right dominance of(More)
The high number of knee imaging exams at radiology clinics, together with the wide variety of knee disorders, calls for expanding the knowledge about the less common lesions seen in routine diagnostic practice. The purpose of this pictorial essay was to illustrate unusual lesions that distend the knee joint, selected by relevance and evaluated with multiple(More)
