The tumor is in the right lobe of the cerebellum
where I also have a developmental venous
anomaly/venous angioma. I recently underwent
surgery during which approxamitely 70 percent
of the tumor was removed. The remaining tumor

vessels that are feeding that area are also
feeding healthy cells.
My medical team has suggested having
the Gamma Knife procedure to target the
remaining tumor cells. The tumor is located
in a small and limited area.
I would like to know your opinion of the
- How many of your patients have developed necrosis following
Gamma Knife radiosurgery? Is necrosis
more likely since I already had the
cycle or radiation with chemotherapy?
- Could the Gamma Knife help to occlude
the veins of the angioma since part of
them are feeding both the tumor and normal
Dr. Lee responds:
Gamma Knife radiosurgery is useful as an
adjunct to cranial surgery and traditional
radiation treatment in the management
of recurrent glioblastoma.
In response to your question about necrosis,
in general, we follow established guidelines
to maintain necrosis at a level less than
