Incidental detection of left ventricular metastasis from lung squamous cell carcinoma on FDG PET/CT: A rare case report.
Article in Asia Oceania journal of nuclear medicine & biology, 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
Cardiac metastases are uncommon, particularly in the left ventricle, where lesions often remain asymptomatic and can be easily overlooked on conventional imaging. Lung cancer, a leading cause of global cancer-related morbidity and mortality, accounts for approximately one-third of all cases of cardiac metastases among various malignancies. We present a 62-year-old male with stage IV squamous cell carcinoma of the lung, who exhibited widespread systemic metastases. Staging Fluorine-18 Fluorodeoxyglucose (¹⁸F-FDG) Positron Emission Tomography/Computed Tomography (PET/CT) revealed a hypermetabolic cavitary left upper lobe mass with a metastatic process involving multiple nodal, adrenal, hepatic, osseous, and cerebral deposits, along with an incidental focal FDG-avid lesion in the left ventricle that was not detected on initial CT. Echocardiography confirmed preserved cardiac function with a normal ejection fraction. Given uncommon nature of left ventricular involvement by squamous cell carcinoma and the limited number of similar reported cases, our findings contribute to the growing evidence supporting the critical role of ¹⁸F-FDG PET/CT in detecting clinically silent occult cardiac metastasis.
