Awake craniotomy with functional mapping for recurrent high-grade IDH-mutant glioma during pregnancy: illustrative case.
Article in Journal of neurosurgery. Case lessons, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAlthough gliomas during pregnancy are rare, they present significant clinical and ethical challenges due to the potential effects of pregnancy on tumor behavior and the risks associated with the standard of care. Given the peak incidence of IDH-mutant glioma in the 3rd and 4th decades of life, clinicians face a challenge in balancing maternal oncological outcomes with fetal safety, while navigating the uncertainty surrounding the effects of standard treatment modalities on fetal development. OBSERVATIONS: A 31-year-old woman at 23 weeks of gestation with a history of IDH-mutant glioma presented to the authors' institution with worsening neurological symptoms. MRI indicated tumor progression, and re-resection was performed via awake craniotomy with functional mapping. The maternal-fetal medicine team was consulted to guide the selection of anesthesia and optimize intraoperative positioning, ensuring the safety of both the patient and fetus. Postoperative recovery was uneventful, with stable maternal and fetal outcomes. Pathological analysis confirmed progression to a grade 4 astrocytoma. LESSONS: This case highlights the feasibility of awake craniotomy with functional mapping during pregnancy. Management of gliomas in pregnancy requires a multidisciplinary approach, balancing maternal health and fetal safety, with careful consideration of treatment timing and anesthetic strategies. https://thejns.org/doi/10.3171/CASE2696.
