Case Description: A 63-year-old man, who had undergone left STA-MCA anastomosis in the treatment of occlusion of internal carotid artery 4 years ago, presented with a hyperintense lesion on T2-weighted image in the left frontal lobe, the perfusion territory of the prior bypass. Follow-up magnetic resonance imaging 1 month later showed enhanced tumor within the T2 hyperintense lesion. A total removal of the tumor through another craniotomy was performed. The pathologic diagnosis was metastatic carcinoma. Conclusion: This is the first report of the metastatic carcinoma by seeding of tumor cells through STA-MCA bypass flow.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/6e993946-d0cf-4d1d-bb0c-004f34a269f1/featured/hero-1782420951271.png","publishDate":"2015-11-25T00:00:00.000Z","doi":"10.4103/2152-7806.170468","categories":["Unique Case Observations","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/6e993946-d0cf-4d1d-bb0c-004f34a269f1/pdf"}
