Case Description: The patient was a 17-year-old male adolescent who was diagnosed as having a posterior fossa medulloblastoma when he was 8 years old. He had undergone tumor resection with radiotherapy and chemotherapy. A distal posterior inferior cerebellar artery aneurysm was identified by magnetic resonance imaging 8 years after radiotherapy and grew rapidly throughout the next 1 year. The patient underwent microsurgical clipping and was discharged without deficit. Conclusion: This experience demonstrates that physicians caring for patients who have undergone intracranial radiotherapy should carefully consider the possibility of an aneurysmal formation when conducting follow-up imaging.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/3dac4cda-acb4-4c8d-8ff5-bc27c6ead949/featured/hero-1782420831753.png","publishDate":"2016-11-21T00:00:00.000Z","doi":"10.4103/2152-7806.194501","categories":["Unique Case Observations","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/3dac4cda-acb4-4c8d-8ff5-bc27c6ead949/pdf"}
