INTRODUCTION Sinus pericranii (SP) is a rare, usually asymptomatic condition characterized by a large communication between the intra- and the extracranial venous drainage pathways in which blood may circulate bidirectionally through dilated veins of the skull. We describe our diagnostic and therapeutic experience with SP, with a special focus on the(More)
Foreign material emboli following cerebral, cardiac, and peripheral catheterizations have been reported since the mid-1990s. Catheter coatings have been frequently implicated. The most recent surge of interest in this phenomenon within the neurointerventional community is associated with procedures using flow-diversion devices for the treatment of cerebral(More)
RATIONALE It is known that epilepsy has a severe impact in the quality of life of the patients; however, it affects the lives of all family members. The psychosocial repercussions of epilepsy are often of greater significance than the seizures themselves. METHODS This was a prospective study, conducted from January 2005 to December 2005 at the pediatric(More)
While multiple intracranial arterial aneurysms occur in 26.4% of patients with aneurysms, in our practice bilateral mirror-like aneurysms are encountered in 9.4% of patients. Multiple mirror aneurysms in the same patient are exceedingly rare. We report a case of mirror-like middle cerebral artery aneurysms associated with mirror-like posterior inferior(More)
BACKGROUND We describe two previously unreported cases with complete or incomplete expression of PHACES syndrome, a rare congenital syndromal pediatric disorder, which is characterized by posterior cranial fossa malformations, large facial hemangiomas, arterial anomalies, coarctation of the aorta and cardiac defects, abnormalities of the eye, sternal and(More)
Basilar artery "fenestration" is the result of a failed fusion of the bilateral longitudinal neural arteries and can be associated with a saccular aneurysm, which typically arises at the proximal juncture of the unfused segment. "Kissing" aneurysms at this site, i.e. two aneurysms arising from the proximal junction of the unfused segment of the basilar(More)
SUMMARY Carotid cavernous fistulas (CCF) are mostly post-traumatic and are due to a tear of the internal carotid artery (ICA) inside the cavernous sinus. The improvement of endovascular techniques with venous approach enables the preservation of internal carotid artery patency in most cases when detachable balloons fail in order to reconstruct and repair(More)
BACKGROUND AND PURPOSE The most common causes of parkinsonism are degenerative and irreversible. Structural causes of reversible parkinsonism are exceptionally rare, but have been reported in association with deep cerebral venous thrombosis and dural arteriovenous fistula (DAVF). We now report a case of parkinsonian syndrome reversed by treatment of a dural(More)
SUMMARY Within the group of giant and large aneurysms the subgroup of the so-called "partially thrombosed" aneurysms can be differentiated according to clinical and neuroimaging findings. The present study was carried out to determine the site of bleeding of these aneurysms and what implications concerning their pathomechanism can be drawn from these(More)
OBJECTIVES To compare computed tomography (CT) with magnetic resonance imaging (MRI) for the presumptive diagnosis and localization of acute and subacute low-grade subarachnoid hemorrhage (SAH). METHODS We consecutively enrolled 45 patients clinically suspected of low-grade SAH, comparing them with a control group. We obtained axial nonenhanced CT scans(More)
