Abstract
Background Synchronous cerebellopontine angle (CPA) tumors are a rare entity. Several publications
refer to surgery for such tumors and their classification. Yet, there are no publications
on upfront radiosurgery for synchronous CPA tumors.
Case Description The authors present two patients with sporadic synchronous benign CPA tumors who
underwent upfront radiosurgery. One patient had two separate schwannomas of the CPA
and the other had a schwannoma and a meningioma of the CPA. One patient underwent
stepwise radiosurgery treating one tumor after another and the other patient underwent
simultaneous radiosurgery for both tumors at the same time.
Conclusion Simultaneous and stepwise radiosurgery for synchronous CPA tumors seems to be safe
and effective. There were no side effects or complications. To the best of our knowledge
this is the first report on upfront radiosurgery for synchronous CPA tumors.
