Primary cerebellar angiosarcoma: a rare case report and literature review.
Review in BMC surgery, 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
backgroundAngiosarcoma is a highly aggressive malignant mesenchymal tumor, accounting for less than 1% of all soft tissue sarcomas. While most cases arise in the skin, soft tissues, liver, or heart, primary intracranial angiosarcoma (PIA) is an exceptionally rare and distinct clinicopathological entity. Due to nonspecific clinical presentations and imaging features, PIA poses significant diagnostic and therapeutic challenges. It is characterized by aggressive behavior, with high rates of recurrence and metastasis, resulting in poor overall prognosis. Here, we report a rare case of primary cerebellar angiosarcoma and review its epidemiology, pathogenesis, diagnostic considerations, and treatment strategies. CASE PRESENTATION: A 53-year-old woman presented with progressive dizziness, occipital headache, nausea, and vomiting for five days. MRI revealed a hemorrhagic, highly vascular right cerebellar mass initially suspected to be a hemangioblastoma. Prior to surgery, her condition deteriorated, and emergency CT showed acute tumor hemorrhage, necessitating urgent resection. Intraoperatively, the tumor was highly vascular and poorly circumscribed, suggestive of a high-grade sarcoma, later confirmed as angiosarcoma. Despite gross total resection, the patient remained comatose due to brainstem compression. Follow-up CT on day 20 revealed rapid tumor recurrence. Given the poor prognosis, the family opted for palliative care, and the patient subsequently passed away.
conclusionPIA is a rare and aggressive tumor with a poor prognosis, characterized by rapid progression and recurrence. Early detection and surgical resection are essential, but effective adjuvant therapies remain limited. A multidisciplinary approach is crucial to improve outcomes, and further research is needed to refine therapeutic strategies and enhance survival.
