Case Description: Here, we present the case of a 64-year-old man who underwent SRS for a relatively large dumbbell-shaped left jugular foramen schwannoma (JFS) and thereafter developed intratumoral hemorrhage. On post-SRS day 3, he developed lower cranial nerve palsies with radiographically evident tumor expansion. His neurological conditions had gradually improved thereafter; however, he suddenly developed headache, dizziness, and mild hearing deterioration at 7 months due to intratumoral hemorrhage. We managed the patient conservatively, and eventually, his symptoms improved except for slight ataxia and hearing deterioration. Follow-up images at 4 years from SRS demonstrated significant tumor shrinkage. This is the first report describing intratumoral hemorrhage after SRS for JFS. Conclusion: Transient expansion of the tumor and subsequent venous stasis around the tumor may have played a role in the hemorrhage. Intratumoral hemorrhage should be considered as a rare, but potential complication of SRS for JFSs.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/47e02f7a-097e-46ad-846c-d3635f0543f6/featured/hero-1781561977540.png","publishDate":"2021-09-30T00:00:00.000Z","doi":"10.25259/SNI_550_2021","categories":["Neuro-oncology","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/47e02f7a-097e-46ad-846c-d3635f0543f6/pdf"}
