Natural history of multiple meningiomas
Date of publication: 28-May-2013
Background:Asymptomatic solitary meningiomas are typically managed with clinical and radiographic follow-up. Multiple meningiomas represents a clinical entity distinct from solitary meningiomas and can be sporadic, radiation-induced, associated with neurofibromatosis, or exhibit other familial inheritance. The growth rate for multiple meningiomas is not known and therefore management of these complicated patients can be difficult.
Variations in the Anatomy of the Willis’ circle: A 3-year cross-sectional study from Iran (2006-2009). Are the distributions of variations of circle of Willis different in different populations? Result of an anatomical study and review of literature
Date of publication: 17-May-2013
Background:It is not well known whether the distributions of variations of circle of Willis (CW) are different in different populations. Previous studies have indicated: (a) The variations of the structure of the CW in different populations and ethnic and (b) some correlation between those congenital anatomical variations and possible cerebrovascular diseases. The frequency of such anatomical variations has not been evaluated sufficiently in the Iranian population. The aim of this study is to find the variations of the anatomy of the vessels in the CW in sample population of Iranian people and compare it with other available studies in the literature, providing a new grouping for variations.
Selective excision of cerebral metastases from the precentral gyrus
Date of publication: 17-May-2013
Background:The surgical management of cerebral metastases to the eloquent cortex is a controversial topic. Precentral gyrus lesions are often treated with whole brain radiation therapy (WBRT) or stereotactic radiosurgery (SRS) because of the concern for causing new or worsened postoperative neurological deficits. However, there is evidence in the literature that radiation therapy carries significant risk of complication. We present a series of patients who were symptomatic from a precentral gyrus metastasis and underwent surgical excision.
Experience with 25 years of dorsal root entry zone lesioning at a single institution
Date of publication: 17-May-2013
Background:The authors sought to assess long-term efficacy, surgical morbidity, and postoperative quality of life in patients who have undergone dorsal root entry zone (DREZ) lesioning.
Anterior clinoid mucocele presenting with orbital apex syndrome
Date of publication: 09-May-2013
Background:Pneumatized anterior clinoid process is a common anatomic variant. Mucocele formation is a known complication of clinoid drilling during certain intracranial operations; however, mucoceles of pneumatized anterior clinoid processes have been found to spontaneously occur.
The incidence and risk factors for postoperative urinary retention in neurosurgical patients
Date of publication: 24-Apr-2013
Background:Postoperative urinary retention (POUR) is a common problem in adult neurosurgical patients. The incidence of POUR is unknown and the etiology has not been well established. POUR can lead to urogenital damage, prolonged hospital stay, higher cost, and infection. This study elucidates several risk factors that contribute to POUR in a variety of neurosurgical patients in one institution.
Strategic design for pediatric neurosurgery missions across the Western Hemisphere
Date of publication: 24-Apr-2013
Background:With growing interest in global health, surgeons have created outreach missions to improve health care disparities in less developed countries. These efforts are mainly episodic with visiting surgeons performing the operations and minimal investment in local surgeon education. To create real and durable advancement in surgical services in disciplines that require urgent patient care, such as pediatric neurosurgery, improving the surgical armamentarium of the local surgeons must be the priority.
Intracranial granuloma mimicking a brain tumor in a patient with scleroderma
Date of publication: 18-Apr-2013
Background:Intracranial granulomatous masses presenting as space occupying lesions, although rare, have been described in the literature. Causes include infections, systemic granulomatous disorders, and iatrogenic from previous surgery. We present a case demonstrating that spontaneous intracranial granuloma can exist, often mimicking a brain tumor.
Hemangiopericytoma of neck extending to craniovertebral junction treated by surgery, pre- and postoperative radiotherapy
Date of publication: 18-Apr-2013
Background:Hemangiopericytoma (HPC) is a rare tumor of uncertain malignant potential arising from mesenchymal cells with pericytic differentiation. It accounts for 3-5% of soft tissue sarcomas, and 1% of vascular tumors. The treatment of choice is a primary wide surgical resection with adjuvant radiotherapy (RT) reserved for cases of incomplete removal.
