Case in brief
An 82-year-old woman presented with dizziness, and evaluation identified two left atrial masses, including pulmonary vein involvement. The masses were resected with clear margins; no metastases were initially found. She subsequently developed widespread delayed metastases and died 279 days after surgery. The case was diagnosed as primary cardiac spindle cell sarcoma.
What made this case unusual
The tumor presented as dual left atrial masses with pulmonary vein involvement, and widespread metastases developed after resection despite clear margins and no initial evidence of metastasis.
Diagnostic / clinical pearl
Clear-margin resection and absence of detectable metastases initially did not prevent delayed widespread metastatic disease in this patient with cardiac spindle cell sarcoma.
Why it matters
The report underscores the need for vigilant follow-up and multidisciplinary care after resection, as emphasized by the authors.
