Giant Lumbosacral Meningioma Without Dural Attachment in an Adolescent: A Rare Diagnostic and Surgical Challenge.
Article in International medical case reports journal, 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
Objective: To present a rare case of a huge, nondural-based atypical lumbosacral meningioma. Background: Meningiomas are dural-based tumors that originate from arachnoid cap cells of the dural sac. Their clinical presentation is mainly due to compression of the neighboring neural structures. Management of meningiomas includes maximal surgical resection with/without radiation therapy. Herein, we present the 24th case of nondural-based, giant, lumbosacral meningioma in a young girl, a presentation that could be considered as the rarest presentation of meningiomas. Case Presentation: The patient was a 13-year-old girl with persistent low back pain and walking difficulty for one month before our visit, without any response to conservative therapy. Imaging studies showed a huge lumbosacral meningioma at the level of L3 to S3 vertebrae. Results: Tumor was completely resected through a posterior spinal approach. The post-operative course lacked any significant morbidity. In her one-year follow-up, complete neurological recovery without cerebrospinal fluid (CSF) leakage and any sign of regrowth of the tumor was documented. The pathologic investigation revealed meningioma grade 1 (WHO 2021 classification). Conclusion: We presented a rare case of lumbosacral, non-dural based meningioma (WHO Grade I), which is atypical in terms of size, location, and severe adhesion to spinal nerve roots and the dura.
