Is there any evidence that radiotherapy can worsen balance, dizziness, or vertigo in patients treated for vestibular schwannoma due to transient edema?

While the answer from Dr. @Dr. First Last addresses a much broader category of patients treated with SRS, we have looked specifically at post radiation side effects after treatment of vestibular schwannomas treated with either SRS (12.5 Gy), hypofractionated SRS (hSRT with 5 fractions of 5 Gy), or conventionally fractionated RT (54 Gy). The patients were treated at a single institution by one physician and using the Novalis Unit with micro MLC. We found that post-radiation complications occurred...

Post-SRS Acute Symptomatic Worsening in Vestibular Schwannoma

Minesh Mehta, @Dr. First Last, @Dr. First Last, and Michael Mcdermott

Acute symptomatic worsening after SRS or FSRT for vestibular schwannoma is uncommon and hence, there are no great databases to answer this question with precision. In 2004, we reported on acute sequelae of stereotactic radiosurgery (Hong et al, Radiosurgery 2004), as we had recognized that few reports, had specifically analyzed or focused on the immediate sequelae f...
