Case Description: We report a 22-year-old woman admitted with headache, papilledema, vision loss, and a history of leukemia. Lumbar puncture revealed idiopathic intracranial hypertension (IIH). Three months after VPS implantation, she was readmitted with headache and worsening of visual impairment. CT evidenced a IPC with perilesional edema. Intraoperatively, a shunt revision and cyst drainage were opted for. We present a discussion and literature review on this unique complication of VPS, with emphasis on management. Conclusion: It is important to understand and consider IPCs as complications of VPS surgery, including in adult patients and IIH cases.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/420fd93c-fa55-4f38-8b8b-16461ccde9f0/featured/hero-1781561384706.png","publishDate":"2022-05-06T00:00:00.000Z","doi":"10.25259/SNI_180_2022","categories":["General Neurosurgery","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2022/05/11577/SNI-13-195.pdf"}
