Pachymeningeal en plaque metastasis from gastric cancer mimicking subdural hematoma: illustrative case.

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
backgroundPachymeningeal metastasis associated with gastric cancer, especially in its early stages, is extremely rare. OBSERVATIONS: The authors describe a 77-year-old man with a past medical history of lung cancer and previously treated chronic subdural hematoma who was admitted to their hospital because of hematemesis and newly diagnosed gastric cancer. He became unconscious during the hospitalization. The preoperative brain imaging studies had the appearance of recurrent subdural hematoma and extracranial tumor with skull invasion. Craniotomy revealed pachymeningeal carcinomatosis and en plaque metastasis of tumor. The histopathology of the tumors was consistent with metastatic gastric adenocarcinoma. LESSONS: This is the first reported case of metastatic gastric cancer as a pachymeninges-based en plaque entity. This report highlights the rare radiological presentation and operative findings in this case. The authors also summarize those case reports associated with dural metastasis arising from gastric cancer.
