Adjuvant irradiation of the resection cavity after craniotomy is a newer application of stereotactic radiosurgery. This technique has been proposed to avoid long-term neurotoxicity of whole-brain radiation therapy, and seems to afford comparable local control rates in the multiple published retrospective series so far. Currently, many questions remain to be answered to define the optimal patien...

Radiotherapy (RT) remains an effective treatment in patients with acromegaly refractory to medical and/or surgical interventions, with durable tumor control and biochemical remission; however, there are still concerns about delayed biochemical effect and potential late toxicity of radiation treatment, especially high rates of hypopituitarism. Stereotactic radiotherapy has been developed as a mo...

A patient with a severe kyphotic deformity presented for Stereotactic radiosurgery. In the supine position with the apex of the patient's kyphosis on the treatment couch, his head and buttocks were found to be approximately 30 cm from the table. Pretreatment consultation with the physicist and engineer was arranged. By creating a modified table mount for the head ring and a custommolded Styrofo...

Over the past several decades, stereotactic radiosurgery has become a viable noninvasive treatment option for patients with trigeminal neuralgia. The scientific literature regarding the radiosurgical treatment of trigeminal neuralgia has evolved to identify factors that predict both efficacy and toxicity. Radiosurgical management has, thus, become complementary to medical management, microvascu...

Introduction: Cerebral cavernous malformations (CMs), also known as cavernomas, are brain vascular anomalies that consist of clusters aberrant, hyalinized capillaries surrounded by hemosiderin deposits and a gliotic border. CMs cavernomas. The vasculature is filled with blood can exhibit varying degrees thrombosis. familial form inherited in an autosomal dominant manner caused heterozygous muta...

introduction polymer gel dosimeters offer a practical solution to 3d dose verification for conventional radiotherapy as well as intensity-modulated and stereotactic radiotherapy. in this study, egsnrc calculated and pagat polymer gel dosimeter measured dose profiles from single shot irradiation with 18 mm collimator of gamma knife in homogeneous and inhomogeneous phantoms were compared with eac...

Growth hormone (GH)-secreting pituitary adenomas represent a common source of GH excess in patients with acromegaly. Whereas surgical extirpation of the culprit lesion is considered first-line treatment, as many as 19% of patients develop recurrent symptoms due to regrowth of previously resected adenomatous tissue or to continued growth of the surgically inaccessible tumor. Although medical the...

Stereotactic radiosurgery (SR) represents an increasingly utilized modality in the treatment of intracranial and extracranial pathologies. Stereotactic spine radiosurgery (SSR) uses an alternative strategy to increase the probability of local control by delivering large cumulative doses of radiation therapy (RT) in only a few fractions. SSR in the treatment of intramedullary lesions remains in ...

Brain metastases are an increasingly common complication in patients with systemic cancer. The optimal treatment for each patient depends on careful evaluation of several factors: the location, size, and number of brain metastases; the patient's age, general condition, and neurologic status; and the extent of systemic cancer to name a few. For patients with a single brain metastasis and limited...
