Only seven cases of brain metastasis from UC have been reported in the literature thus far. Case Description: A 77-year-old female was diagnosed with a brain tumor in her left cerebellum 2 years after she underwent surgery for a primary UC in the bladder. Surgery was performed via a midline suboccipital approach and the tumor was totally removed. The excised lesion was pathologically diagnosed as a metastasis and displayed typical pathological features of urachal adenocarcinoma with abundant mucin mixed with signet ring cells. A recurrence was observed at the site of tumor removal 6 months after surgery, and then, gamma knife radiotherapy was performed to the lesion. Conclusion: According to the five previously reported similar cases and our case, tumor removal is the treatment of choice. Routine whole brain radiotherapy is not the best treatment choice; however, local radiotherapy including conventional local radiotherapy or gamma knife radiotherapy could be implemented instead.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/fab9fca7-8044-4989-8371-8bbfe1ff7ad2/featured/hero-1781563814599.png","publishDate":"2019-08-02T00:00:00.000Z","doi":"10.25259/SNI_79_2019","categories":["Neuro-oncology","Case Report"],"fullTextUrl":"http://surgicalneurologyint.com/wp-content/uploads/2019/08/9556/SNI-10-152.pdf"}
