Periampullary Carcinoma Presenting as Chronic Subdural Hematoma: A Rare Case Report.
Article in Annals of African medicine, 2026. 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
abstractSkull metastases usually arise from breast and lung primaries and are often silent. Spread from periampullary carcinoma is exceedingly rare. We present a 46-year-old female with a history of periampullary carcinoma, previously treated with surgery and chemotherapy, who presented with headache, vomiting, and declining consciousness. At admission, she was in a stuporous state. Computed tomography (CT) revealed a large right frontoparietal subdural hematoma (SDH) with midline shift. Emergency burr hole evacuation exposed fragile bone and hemorrhagic tissue; biopsy confirmed metastatic adenocarcinoma. Retrospective review of bone windows revealed lytic lesions consistent with skull metastasis. This appears to be the first documented case of periampullary carcinoma metastasizing to the skull and presenting as spontaneous SDH, without trauma, coagulopathy, or anticoagulant use. Early recognition with magnetic resonance imaging and positron emission tomography-CT is vital. This case highlights the importance of considering skull metastasis as an etiology of intracranial hemorrhage in oncologic patients.
