Diffuse Pulmonary Meningotheliomatosis Presenting as Innumerable Pulmonary Micronodules: A Case Report.
Article in Thoracic cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Diffuse pulmonary meningotheliomatosis (DPM) is a rare lung condition characterized by widespread meningothelial-like nodules and may radiologically mimic metastatic or granulomatous disease. We report a 2019-onset case of a 44-year-old woman with incidentally detected, bilateral 1-2-mm pulmonary micronodules on screening CT. Laboratory tests and pulmonary function were normal. Owing to the minute, peripheral distribution of the nodules, bronchoscopic biopsy was not feasible, and diagnostic video-assisted thoracoscopic wedge resection was undertaken. Histology showed spindle-to-ovoid cells in whorled arrangements without atypia or mitoses. Immunohistochemistry revealed diffuse vimentin positivity and negativity for epithelial and neuroendocrine markers (EMA, cytokeratin AE1/AE3, SMA, chromogranin). Postoperative brain MRI showed no intracranial lesion. The patient has remained asymptomatic without radiologic progression over 3 years. This case underscores DPM as an uncommon yet important differential diagnosis of diffuse pulmonary micronodules and highlights the need for histopathologic confirmation when bronchoscopic sampling is impracticable. Where available, PR and SSTR2A immunostains may further support the diagnosis.
