Prostate adenocarcinoma dural metastasis mimicking a subacute subdural hematoma.
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: Patients with malignancies that have a propensity to develop dural metastasis can present a dural infiltration mimicking a subdural hematoma. Dural metastases originating from prostate cancer mimicking a subdural hematoma are rare. Case Description: The authors describe the case of a 66-year-old man with a history of prostate adenocarcinoma with vertebral metastases who complained of headaches, weakness, anorexia, and dizziness for 1 month. A head computed tomography scan without contrast demonstrated a right pan-hemispheric subdural collection, which was reported to be a subacute subdural hematoma. Due to the patient's history of prostate carcinoma, brain magnetic resonance imaging (MRI) with and without gadolinium was requested before the surgery, which showed substantial enhancement of the subdural collection, suggesting a tumoral collection. Based on the MRI findings, an open biopsy was performed, revealing extensive bone infiltration and a thickened dura with a large subdural tumoral component suggestive of disseminated pachymeningeal carcinomatosis. No hematoma was identified. Conclusion: This case report demonstrated how metastatic lesions can mimic subdural hematomas. This disease carries a poor prognosis. Diagnosing and managing this rare entity warrants high suspicion to guide the patient and the family members in decision-making.
