Summary
Radiotherapy (RT) can be an effective standalone treatment for recurrent intracranial epidermoid cysts when surgery is not an option. This case shows a delayed positive response to RT, with initial worsening followed by gradual improvement and tumor regression.
Area of Science:
- Neurosurgery
- Radiation Oncology
- Oncology
Background:
- Intracranial epidermoid cysts frequently recur after surgical resection.
- Recurrence necessitates alternative treatment strategies, especially when further surgery is not feasible.
- Management of recurrent cerebellopontine angle epidermoid cysts presents significant challenges.
