Purely Epidural Thoracic Meningioma With Elevated Ki-67 in a Postmenopausal Female With Prior Gynecologic Malignancies: A Case Report.
Article in Cureus, 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
Meningiomas are common central nervous system (CNS) tumors; however, purely epidural spinal meningiomas are an exceedingly rare subtype. Their differentiation from other extradural lesions, particularly in patients with a history of malignancy, remains a diagnostic challenge. Additionally, the potential influence of hormonal factors on meningioma development is not fully understood. Here, we present the case of a 60-year-old female with a purely epidural thoracic meningioma, notable for its occurrence after a history of stage IA endometrial and ovarian cancer. Despite its classification as a World Health Organization (WHO) Grade 1 meningioma, the tumor exhibited an elevated Ki-67 index of 4.5%, a finding rarely documented in purely extradural spinal meningiomas. This case contributes to the limited literature on extradural meningiomas and raises questions about the biological behavior of such tumors, particularly in patients with prior gynecologic malignancies and hormone replacement therapy exposure. This case underscores the importance of considering oncologic history and hormonal influences in the evaluation of spinal tumors. It also highlights the diagnostic and management challenges associated with purely epidural meningiomas and emphasizes the potential role of Ki-67 as a prognostic marker in extradural lesions. Further research is warranted to explore the interplay between hormonal factors and meningioma pathogenesis.
