OBJECT To evaluate long-term outcomes of patients who have undergone stereotactic radiosurgery for cavernous sinus meningiomas, the authors retrospectively reviewed their 14-year experience with these cases. METHODS One hundred seventy-six patients harbored meningiomas centered within the cavernous sinus. Seventeen patients were lost to follow-up review,(More)
OBJECT Pituitary adenomas are very common neoplasms, constituting between 10 and 20% of all primary brain tumors. Historically, the treatment armamentarium for pituitary adenomas has included medical management, microsurgery, and fractionated radiotherapy. More recently, radiosurgery has emerged as a viable treatment option. The goal of this research was to(More)
In this chapter we show that the organization of the communication and memory infrastructures is critical in today’s complex systems-on-chip (SOCs). We further show that resource management in the form of scheduling or arbitration is common to them both. The increasing importance of these issues is illustrated by following the evolution of an advanced(More)
OBJECTIVE To evaluate the role of stereotactic radiosurgery (SRS) in the management of recurrent or residual intracranial hemangioblastomas, we assessed tumor control, survival, and complications in 32 consecutive patients. METHODS We retrospectively reviewed records of 32 consecutive hemangioblastoma patients (74 intracranial tumors) who underwent gamma(More)
OBJECTIVE Stereotactic radiosurgery has become an important primary or adjuvant minimally invasive management strategy for patients with intracranial meningiomas with the goals of long-term tumor growth prevention and maintenance of patient neurological function. We evaluated clinical and imaging outcomes of meningiomas stratified by histological tumor(More)
OBJECT Pituitary adenomas are fairly common intracranial neoplasms, and nonfunctioning ones constitute a large subgroup of these adenomas. Complete resection is often difficult and may pose undue risk to neurological and endocrine function. Stereotactic radiosurgery has come to play an important role in the management of patients with nonfunctioning(More)
To assess outcomes when stereotactic radiosurgery (SRS) is used during multimodality management of pilocytic astrocytomas in adult patients. Fourteen patients (six male and eight females) with pilocytic astrocytomas underwent SRS between 1994 and 2006. The median patient age was 32 years (range, 19–52 years). Initial surgical management included(More)
To assess outcomes after stereotactic radiosurgery (SRS) for newly diagnosed or recurrent pilocytic astrocytomas in pediatric patients. Fifty patients (28 male and 22 females) with juvenile pilocytic astrocytomas (JPA) underwent Gamma knife SRS between 1987 and 2006. The median patient age was 10.5 years (range, 4.2–17.9 years). Three patients had failed(More)
OBJECTIVE The optimal management of intracranial arteriovenous malformations (AVMs) in children remains controversial. Children with intracranial AVMs present a special challenge in therapeutic decision-making because of the early recognition of their future life-long risks of hemorrhage if they are treated conservatively. The goals of radiosurgery are to(More)
OBJECT Management options for vestibular schwannomas (VSs) have greatly expanded since the introduction of stereotactic radiosurgery. Optimal outcomes reflect long-term tumor control, preservation of cranial nerve function, and retention of quality of life. The authors review their 15-year experience. METHODS Between 1987 and 2002, some 829 patients with(More)
