Does stereotactic radiosurgery work for a cavernous malformation?

Does stereotactic radiosurgery work for a cavernous malformation?

Yes: Generally speaking, abnormal blood vessels formation such as cavernous malformation or aterio-venous malformation can be treated with surgery, embolization or stererotactic radiosurgery (srs). Intracranial lesions are risky because bleeding from those can cause stroke or even death. Srs with gamma knife or linear based external srs are both effective. Contact neurosurgery and radiation docs. ...Read more

Which is better for pituitary macroadenoma: transsphenoidal surgery or craniotomy?

Depends: Assuming it is an operative mass: this really depends on what the tumor looks like on imaging. Most of these masses can be done via transphenoidal approach with microscope or endoscope. Rarely it gets so large and if the patients medical condition is ok can be done via combined transphenoidal and craniotomy. Patients recover from transphenoidal surgery more quickly than craniotomy. ...Read more
