چکیده
The management of pineal region tumors has changed considerably since the introduction of microsurgery and CT scanning. Analysis of our own series of 36 patients, comparing those treated in the pre-CT scan and microsurgery era with those treated afterwards, shows the important role these two techniques play. Current controversies in treatment and our own approach to management of pineal region tumors are discussed.
