In general, [[SRS]] is useful for well-circumscribed lesions less than approximately 3 cm in diameter. For larger lesions, the [[radiation]] dose must be reduced because of anatomic and radiobiological constraints.

Published uses of SRS include: 

● vascular lesions

○ [[Intracranial arteriovenous malformation]]s (AVMs)(including dural arteriovenous fistulas)

○ cavernous malformations 

● tumors

○ [[metastases]]:

see [[Stereotactic radiosurgery for Brainstem metastases]]

○ vestibular schwannomas

○ see [[Stereotactic Radiosurgery for intracranial meningioma]]

○ [[pituitary neuroendocrine tumor]]s

○ [[glioma stereotactic radiosurgery]]

○ others: craniopharyngioma, pineal tumors, etc.

● functional disorders

○ trigeminal neuralgia

○ intractable chronic pain: thalamotomy

○ movement disorders: pallidotomy for Parkinson’s disease or thalamotomy for tremor (usually not a technique of choice because of the inability to perform physiologic stimulation before lesioning. Maybe a consideration for the rare patients who cannot undergo placement of a stimulator/lesioning needle)

○ psychiatric diseases (e.g. obsessive-compulsive disorder )

○ epilepsy
