Primary Ewing's sarcoma of the petroclival bone: A case report and literature review.
Article in Surgical neurology international, 2020. 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
backgroundPrimary Ewing's sarcoma (ES) is typically seen within the long bones, vertebrae, or pelvis. Uncommonly, it can be found within the cranium among the rarest locations for primary ES are the skull base, in particular, the petroclival bone. CASE DESCRIPTION: The patient is a 68-year-old female with past medical history of Stage III breast cancer who presented with severe retro-orbital headache and diplopia due to a cranial nerve VI palsy. Magnetic resonance imaging (MRI) revealed a mass at the left petroclival bone with extension into the adjacent left petrous apex and into the posterior aspect of the left cavernous sinus proximal to the carotid artery. The patient subsequently underwent an endoscopic transsphenoidal biopsy. Pathological and molecular analysis supported a diagnosis of ES. The patient then underwent neoadjuvant chemotherapy and radiotherapy. At 12 month-follow-up, her petroclival ES demonstrated significant interval decrease in size on MRI surveillance imaging.
conclusionsThis is the third case of primary ES of the petroclival bone to be reported in the literature. In this patient, management consisted of surgical incisional biopsy followed by adjuvant radiation and chemotherapy. Knowledge and awareness of this type of tumor is important for the skull base surgeon.
