Delayed cerebral metastasis after complete resection of left atrial cardiac myxoma: a case report.
Article in Oxford medical 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
Cardiac myxoma (CM) is the most common benign primary cardiac tumor and is usually curable with complete surgical excision. However, CM can cause systemic embolization, and delayed cerebral metastasis is extremely rare. A 54-year-old woman presented with progressive lower limb weakness and was diagnosed with multiple cerebral infarctions associated with a left atrial pedunculated tumor. The tumor was completely resected under cardiopulmonary bypass and confirmed histopathologically as CM. Seven months later, she developed transient visual disturbances and right-hand weakness. Brain magnetic resonance imaging revealed enlarging lesions inconsistent with vascular territories. Craniotomy and histopathology with calretinin positivity confirmed metastatic myxoma. She underwent stereotactic radiotherapy and remained recurrence-free at 1 year. Even after complete resection of CM, delayed cerebral metastasis may occur. Persistent neurological surveillance and multidisciplinary management are essential for early detection and favorable long-term outcomes in patients with CM.
