Case report: preoperative radiological suspicion of atypical meningioma: A diagnostic challenge.
Article in Radiology case reports, 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
Atypical meningiomas represent a minority of intracranial meningiomas yet carry more aggressive biological behavior and higher recurrence rates, making preoperative differentiation essential for optimal management. We report a 56-year-old female presenting with progressive headaches, drowsiness, and vomiting, with no focal neurological deficits. Brain Magnetic Resonance Imaging (MRI) revealed a dural-based lesion at the posterior falx with cystic components, irregular margins, heterogeneous enhancement, disproportionate peritumoral edema, all suggesting atypicality. Subtotal resection followed by histopathological analysis confirmed a atypical meningioma. This case underscores the pivotal role of comprehensive MRI-including conventional sequences and advanced techniques-in identifying features of atypical meningioma even without definitive brain invasion, thereby guiding appropriate surgical planning and consideration of adjuvant therapy.
