A unique presentation of trigeminal neuralgia related to a central nervous tissue choristoma along the trigeminal nerve root: illustrative case

To the best of the authors' knowledge, this is the first documented case of a central nervous tissue choristoma causing TNa and responding positively to surgical intervention, aside from one previous report that did not specifically use the term "choristoma" in identifying the lesion. This case highlights the challenges involved in diagnosing and managing a rare TNa presentation, with a particular focus on pathology findings. It underscores the potential role of surgery for patients whose condition is resistant to medical intervention. https://thejns.org/doi/10.3171/CASE24384.
