PURPOSE Radiosurgery is an effective treatment for cerebral arteriovenous malformations. We conducted the present study to investigate the feasibility and efficacy of gamma knife radiosurgery for dural arteriovenous fistulas (DAVFs) of the cavernous sinus. METHODS Eighteen patients (12 women and six men; 29-75 years old [mean age, 55 years]) with DAVFs of the cavernous sinus (Barrow's type B:...

BACKGROUND The care of patients with a brain metastasis from unknown primary site is controversial. The authors reviewed the results of stereotactic radiosurgery in this group of patients to better define clinical expectations. METHODS During an 11-year interval, radiosurgery was performed in 421 patients with brain metastases at the University of Pittsburgh. Fifteen patients had solitary or ...

Clinical and Imaging Response to Trigeminal Schwannoma Radiosurgery: A Retrospective Analysis of a 28-Year Experience

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 pituitary adenomas. This study examines the o...

OBJECTIVE The restricted radiation tolerance of the anterior visual pathways represents a unique challenge for ablating adjacent lesions with single-session radiosurgery. Although preliminary studies have recently demonstrated that multisession radiosurgery for selected perioptic tumors is both safe and effective, the number of patients in these clinical series was modest and the length of foll...

surgical resection followed by radiotherapy combined with concurrent and adjuvant temozolomide for glioblastomas and radiotherapy for grade 3 gliomas, local relapse remains the predominant pattern of failure for high grade gliomas. Several studies have reported greater than 70% of recurrences occurring within 2 cm of the original gadolinium-enhanced mass after concurrent radiation and temozolom...

OBJECT Although stereotactic radiosurgery is frequently performed for arteriovenous malformations (AVMs) in deep locations, outcomes after radiosurgery for these patients have not been well studied. The goal of this paper was to study these outcomes. METHODS Between 1990 and 2000, 56 patients underwent radiosurgery for AVMs located in the basal ganglia (10 patients), thalamus (30 patients), o...

Stereotactic Radiosurgery has been widely utilized for the treatment of intracranial lesions, and this paper presents our experience in treating schwannomas Bangladesh. This case series was described to present institutional procedural technique adapted using stereotactic (SRS) by Linear accelerators. since starting radiosurgery program March 2019, we have treated three patients schwannoma. Two...

introduction the gamma knife system is designed solely for non-invasive treatment of brain disorders, and it benefits from stereotactic surgical techniques. dose calculations required in the system are performed by gammaplan code; in this code, brain tissue is considered uniform. in the present study, we evaluated the effect of gamma knife system on the obtained dose through simulating a real h...
