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.
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)
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)
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 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 Unruptured intracranial aneurysms (UIA) have become an issue of greater significance as their detection rates have increased over the years. We present the overall experience of microsurgical clipping of unruptured aneurysms by a single surgeon over a period of more than 16 years. METHODS The clinical and radiological data were(More)
A spinal cordectomy is a treatment option for several disorders of the spinal cord like post-traumatic syringomyelia, spinal cord tumor and myelomeningocele. We have done a systematic analysis of all reported cases of spinal cordectomy to investigate the possible outcomes and complications. A PubMed search was performed for literature published from 1949 to(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)
BACKGROUND Meningiomas are more prevalent with increasing age, and there is no general consensus of surgical management for this group of tumors. The role of resection and the predictors of recurrence of meningiomas in elderly patients have not been well established. The authors reviewed their experience of surgical resection of these tumors in elderly(More)
OBJECTIVE The pterional/frontotemporal orbitozygomatic (FTOZ) approaches are the two widely used procedures for resection of sphenoid wing meningiomas. However, a comparison of outcomes and complications of these two approaches has not been well described yet. Here, we investigated the outcomes, complications and predictors of favorable outcomes of these(More)
