The most common sites of metastasis are the lungs, liver, and bones. Single intracranial metastasis is very rare. Case Description: A 43-year-old woman with a history of surgical removal of ACC 24 years prior presented with Gerstmann syndrome and right hemianopsia. Head magnetic resonance imaging revealed a solitary extra-axial tumor in the left occipital region. The tumor was surgically removed and pathologically diagnosed as a metastasis of cribriform-type ACC. Since she had no other systemic metastasis, she did not receive adjuvant treatment and has remained recurrence-free for 35 months postoperatively. Conclusion: Very late intracranial solitary metastasis of ACC is extremely rare. Due to the risk of delayed recurrence in pathologically confirmed cribriform type ACC, long-term follow-up is recommended.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/0ea783bc-6ba8-4bcd-8d0f-190b34d64228/featured/hero-1781559085392.png","publishDate":"2024-11-15T00:00:00.000Z","doi":"10.25259/SNI_403_2024","categories":["Neuro-oncology","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2024/11/13219/SNI-15-423.pdf"}
