Whorls in the Lung: A Case of Primary Pulmonary Meningioma.
Article in Cureus, 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
A primary pulmonary meningioma (PPM) is an exceptionally rare, usually benign tumour, with only about 50 cases reported worldwide. We describe a 75-year-old Japanese female patient with a strong family history of gastrointestinal malignancy, in whom a solitary upper-lobe pulmonary nodule was incidentally detected. Radiological evaluation, including Fluorodeoxyglucose-Positron Emission Tomography (FDG-PET), suggested malignancy, but wedge resection and histopathological assessment, supported by immunohistochemistry, confirmed PPM. This case highlights the diagnostic challenge of distinguishing PPM from primary lung carcinoma, reinforces the importance of tissue confirmation and exclusion of intracranial disease, and draws attention to the potential role of genetic or environmental factors in its pathogenesis. By documenting a well-characterized case with an atypical upper-lobe location, this report contributes practical insights for clinicians and pathologists in the diagnosis and management of PPM.
