Background: Psychogenic non-epileptic seizures (PNES) are paroxysmal events that share similarities with epileptic seizures but lack epileptic electrical activity. Concurrently, the incidental discovery of arachnoid granulation herniation into dural venous sinuses, typically considered benign, has intrigued researchers, especially when observed in conjunction with paroxysmal events. Case Report: We present a case of a 17-year-old male patient with PNES accompanied by an incidental finding of brain herniation into arachnoid granulation (BHAG). Conclusion: This case highlights the intriguing association between psychogenic non-epileptic seizures and the incidental discovery of arachnoid granulation herniation into dural venous sinuses and emphasizes the importance of appropriately identifying and managing PNES to optimize patient outcomes, while also considering the fascinating incidental imaging findings.
