© 2015 Egyptian Journal of Neurosurgery. All rights reserved Background: Intracranial aneurysms are rare in pediatric age group. Their clinicoradiological features may differ from those in adults. Objective: The aim of this study was to analyze clinical presentation, location and morphological characteristics of pediatric age aneurysm with assessment of feasibility, safety and efficacy of endov...

We present five cases of giant serpentine aneurysms (large, partially thrombosed aneurysms containing tortuous vascular channels with a separate entrance and outflow pathway) and review 28 cases reported in the literature. Giant serpentine aneurysms should be considered as a subgroup of giant aneurysms, distinct from saccular and fusiform varieties, given their unique clinical presentation and ...

BACKGROUND AND PURPOSE Neurofibromatosis type I (NF1) is an autosomal dominant, hereditary, neurocutaneous syndrome purported to be associated with intracranial aneurysms. To study the relationship between NF1 and intracranial aneurysms, we have analyzed all intracranial autopsies of NF1 patients performed at our institution from 1889 to 1999 and analyzed all intracranial aneurysm cases at our ...

Spontaneous, nontraumatic, superficial temporal artery (STA) aneurysms have been rarely reported. We herewith report three cases of spontaneous and true STA aneurysms. All patients, a 65-year-old male, a 76-year-old female, and a 47-year-old female, had no history of head trauma that requires medical attention. Painless, pulsatile, and slowly growing calvarial lump was the symptom leading to im...

BACKGROUND Sixty-four-row multislice computed tomographic angiography (CTA) has great potential for use in vascular studies. The aim of our study was to compare 64-slice CTA with three-dimensional rotational angiography (3DRA) in the detection and characterization of intracranial aneurysms with special attention to smaller (<3-mm) aneurysms. METHODS In a prospective study, a total of 133 pati...

BACKGROUND AND PURPOSE Genetic determinants probably play a role in the development of intracranial aneurysms. We review the present knowledge on this issue. METHODS This work entailed a comprehensive search of the literature, a critical appraisal of the identified papers, and a personal view of limitations and future directions. RESULTS We identified 10 genome-wide linkage studies in famil...

BACKGROUND AND PURPOSE The incidence of wall enhancement of cerebral aneurysms on vessel wall MR imaging has been described as higher in ruptured intracranial aneurysms than in unruptured intracranial aneurysms, but the difference in the degree of enhancement between ruptured and unruptured aneurysms is unknown. We compared the degree of enhancement between ruptured and unruptured intracranial ...

We reviewed current literature on the role of seasonal, meteorological, or circadian factors in ruptured cerebral aneurysms. found that aneurysm rupture most frequently occurs winter and spring, less summer. The highest number aneurysms happens morning, between 8 am 12 pm. data regarding meteorological factors' effect risk are conflicting. However, it should be noted changes barometric pressure...

BACKGROUND AND PURPOSE Initial complete occlusion of very large or giant aneurysms often cannot be accomplished, and most will partially reopen over time. This study was performed to assess the clinical and angiographic outcome of patients with very large or giant cerebral aneurysms treated with detachable coils. METHODS During 6 years, 29 patients with 31 very large or giant (20-55-mm) cereb...

BACKGROUND AND PURPOSE Fenestrations of intracranial arteries are variants resulting from incomplete fusion of primitive vessels. An association with aneurysms is suggested in many studies. On conventional angiography, fenestrations are rarely visible. 3D rotational angiography (3DRA) provides improved visualization of cerebral vessels from any desired angle. We used 3DRA to assess the frequenc...
