OBJECTIVE In this study, we validate the utility of navigation in intracranial meningioma excision and evaluate the effectiveness of image guidance surgery based on clinical outcome, extent of resection, and recurrence-free survival (RFS). METHODS Information related to clinical history, use of neuronavigation, neuroimaging, microsurgical dissection, and(More)
Cysts associated with arteriovenous malformations (AVMs) are either secondary to hemorrhage or after radiosurgery. Untreated and unruptured AVMs with large cysts are rare. We here describe a child with medial parietal AVM associated with cyst, without any history of hemorrhage or radiosurgery. Surgical excision led to cure for the patient.
OBJECTIVE Primary glioblastoma multiforme of the spinal cord is a rare entity. The aim of this study was to perform an integrative analysis of patients whose cases were selected from the published studies, and to examine the influence of various factors on overall outcomes. METHODS A PubMed search was performed for literature published from 1938 to 2015(More)
INTRODUCTION The present study investigates outcomes in patients undergoing elective primary versus revision fusion surgery for lumbar degenerative pathologies with the use of a large population based database. METHODS A total of 126,044 patients registered in the National Inpatient Sample (NIS) database were identified to have undergone elective fusion(More)
OBJECTIVE The clinical significance of the Simpson system for grading the extent of meningioma resection and its role as a predictor of the recurrence of World Health Organization (WHO) Grade I meningiomas have been questioned in the past, echoing changes in meningioma surgery over the years. The authors reviewed their experience in resecting WHO Grade I(More)
OBJECT Ventriculoperitoneal (VP) shunts in infants with posthemorrhagic hydrocephalus (PHH) are prone to failures, with some patients at risk for multiple revisions. The objective of our study is to observe long-term outcomes and identify factors leading to proximal and distal multiple failures. METHODS We performed a retrospective review of infants with(More)
Extraneural metastasis (ENM) in patients with medulloblastoma is a rare but a well-described phenomenon, both in children and adults. Most of the ENM involve bone and bone marrow and rarely involve other solid organs. Subcutaneous and muscular metastasis is an extremely rare event, more so in children, with only two cases documented in the pediatric(More)
We sought to evaluate the outcome of intracranial arteriovenous malformation (AVM) treated with gamma knife radiosurgery (GKRS) (Elekta, Stockholm, Sweden) as a primary treatment as well as an adjunct therapy. GKRS has emerged as an important treatment option for intracranial AVM. However, the long term outcome of GKRS on AVM is not well understood. We(More)
OBJECTIVE The proximal segment of the anterior cerebral artery (A1) is among the most uncommon locations for occurrence of an intracranial aneurysm. These aneurysms may be missed if small or misinterpreted when they are near the internal cerebral artery bifurcation or Anterior Communicating Artery region. The association with congenital vascular anomalies(More)
OBJECTIVE Despite significant advances in the medical field and shunt technology, shunt malfunction remains a nightmare of pediatric neurosurgeons. In this setting, the ability to preoperatively predict the probability of shunt malfunction is quite compelling. The authors have compared the preoperative radiological findings in obstructive hydrocephalus and(More)
