IE is defined as a herniation of the brain parenchyma through a dural defect into the diploic space. Case Description: We present a 59-year-old man with intradiploic cerebellar encephalocele diagnosed in a background of clicks on the head when pressing over the ipsilateral occipital bone. Imaging confirmed right cerebellar brain herniation through the diploic space. Two years of follow-up imaging revealed herniation size progression with no neurology. The patient chose a watch-and-see approach given the potential morbidity of the surgical treatment. Conclusion: Asymptomatic or paucisymptomatic IE does not require surgical treatment. However, both clinicians and patients need to be aware of potential radiological progression during the follow-up period.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/23ee796d-cd55-4dfe-a77b-74aea453237e/featured/hero-1781557999765.png","publishDate":"2026-01-23T00:00:00.000Z","doi":"10.25259/SNI_960_2023","categories":["General Neurosurgery","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2026/01/14247/SNI-17-47.pdf"}
