Stereotactic radiosurgery of intracranial tumors: a comparison of intensity-modulated radiosurgery and dynamic conformational arc.

Purpose: Intensity-modulated radiosurgery (IMRT) and dynamic conformational arc (DCA) are two techniques for linac-stereotactic radiosurgery using the micro-multileaf collimator. The objective of this study is to examine advantages and disadvantages of these techniques in the treatment of treatment of intracranial tumors.

Materials And Methods: SRS treatment plans were developed for 21 patients with vestibular schwannoma, glomus jugulare, pituitary adenoma and cavernous sinus meningioma.

Bilateral malignant metastases to the internal auditory canal: radiosurgical management.

Malignant melanomas constitute 1-8% of all malignant tumors and are the third most common tumor to metastasize to the central nervous system. However, metastases to the cerebellopontine angle (CPA) are rare, accounting for only 0.2 to 0.
