Metastatic osteosarcoma to the squamous temporal bone with intra- and extracranial extension: A case report.
Article in Surgical neurology international, 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: Osteosarcoma is the most common malignant bone tumor in childhood and adolescence. Involvement of the skull is rare, and metastatic spread to the temporal bone has been scarcely described in the literature. In this case report, we present a patient with metastatic osteosarcoma to the squamous temporal bone who underwent successful tumor resection. Case Description: A 19-year-old male with a history of the left tibial osteosarcoma and multiple prior metastases treated with surgery and chemotherapy was admitted for nausea, somnolence, and headache. Imaging demonstrated a large osseous mass of the left squamous temporal bone with intracranial extension causing significant mass effect. He successfully underwent left radical mastoidectomy and left frontotemporal craniotomy for mass resection and cranioplasty. Histopathology confirmed the diagnosis of metastatic osteosarcoma. Conclusion: Osteosarcoma of the skull, particularly arising from metastatic spread, is rare. This case report demonstrates the efficacy of surgery as a means of local control, even in the setting of intracranial extension, and the benefit of multidisciplinary involvement in surgical planning and execution.
