Case report demonstrating radiological progression of polymethylmethacrylate distribution in asymptomatic pulmonary cement embolism.
Article in Radiology case reports, 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
This case report describes a 50-year-old male with metastatic colorectal carcinoma and pathological fractures of T4 and T8 vertebrae, subsequently managed with vertebroplasty. Post-operative day one chest radiograph revealed polymethylmethacrylate (PMMA) extravasation into the azygos vein, but not in pulmonary arteries. Follow-up radiograph in one week showed progressive radiological migration of PMMA into bilateral pulmonary arteries, confirmed by contrast-enhanced computed tomography. The patient remained asymptomatic all along and was under conservative management. Stable cement distribution was maintained afterwards for 5 years. This case highlights the rarely reported radiological progression of cement pulmonary embolism in asymptomatic patient, discusses potential mechanisms and management strategies.
