Radiation-induced meningiomas, cerebral aneurysm, and multiple cavernomas 2 decades after radiotherapy for medulloblastoma: illustrative case.

Key Points

• To emphasize the necessity of long-term monitoring for patients who underwent radiotherapy for medulloblastoma.
• Illustrative case review of a patient treated with radiotherapy.
• Focus on the development of meningiomas, cerebral aneurysms, and cavernomas.
• Discussion of follow-up practices over two decades.
• Patient developed multiple radiation-induced lesions 20 years post-therapy.
• Long-term surveillance showed significant health issues related to prior radiotherapy.
• Need for standardized follow-up protocols remains unanswered.
