Adult-onset intramedullary teratomas: systematic review with outcome analysis.
Synthesis in Acta neurologica Belgica, 2025. 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
BACKGROUND AND
objectiveIntramedullary mature teratomas in adults are rare tumors that pose significant diagnostic and therapeutic challenges due to their diverse tissue composition and intramedullary location. This review, which includes an illustrative case, aims to provide a comprehensive overview of the clinical presentation, diagnosis, treatment, and outcomes of adult intramedullary mature teratomas through a systematic review of 89 cases.
methodsA systematic review was conducted following PRISMA guidelines, using keyword combinations in PubMed, MEDLINE, and Web of Science databases until June 2024. Inclusion criteria were adult patients (> 18 years) with histopathologically confirmed intramedullary mature teratomas. Statistical analyses examined relationships between the extent of resection (EoR), tumor location, and patient outcomes.
resultsAmong the 89 cases, the mean age was 39.94 ± 13.52 years, with a male-to-female ratio of 1.39:1. Tumors were most commonly located in the conus region (51.2%). Surgical resection was the primary treatment, with 43 cases undergoing partial resection and 33 gross total resection. No statistically significant differences in outcomes were found between EoR, sex, associated anomalies, or specific outcomes. However, younger patients showed improved outcomes for lower limb weakness and sphincter dysfunction. Recurrence was noted in three cases, all located in the conus.
conclusionIntramedullary mature teratomas require a nuanced approach that balances complete resection and neurological preservation. Early diagnosis and individualized surgical planning are crucial for optimizing outcomes. Despite the challenges, effective management is achievable, and ongoing research is essential to refining treatment strategies for this rare tumor.
