Nonenhancing intracranial intradural chordoma mimicking an epidermoid cyst on magnetic resonance imaging: a case report.
Article in Radiology case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Chordomas are relatively rare malignant tumors derived from embryonic notochord remnants. Most intracranial chordomas show extradural extension and cause bone erosion. However, a small percentage of these tumors are exclusively intradural and tend to show less aggressive features, although local recurrence and metastatic spread have been described. Intradural chordomas with imaging features similar to epidermoid cysts are exceedingly rare. We describe the case of a nonenhancing and nondestructive intradural prepontine chordoma showing restricted diffusion on magnetic resonance imaging on a 44-year-old man who presented with acute-onset vertigo and vomiting. Subtotal resection of the lesion was performed followed by adjuvant radiation therapy. Histopathological examination revealed a chordoma. This case report highlights the need to include intradural chordomas in the differential diagnosis of a nonenhancing and nondestructive prepontine intradural lesion demonstrating restricted diffusion. Gross total resection, adjuvant radiation therapy in cases of macro/microscopical residual disease and regular follow-up imaging assessment are warranted due to the possibility of local recurrence and metastatic dissemination.
