Insights

A rare case of adult intracardiac blood cysts, usually seen in infants, was successfully resected from a 59-year-old man's right atrium. This finding highlights the potential for these congenital anomalies to persist into adulthood.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Surgical Oncology

Background:

  • Intracardiac blood cysts are typically congenital anomalies found in infants.
  • These cysts usually resolve spontaneously within the first six months of life.
  • They are predominantly located on the left side of the heart and atrioventricular valves.

Observation:

  • A 59-year-old male presented with elevated carcinoembryonic antigen levels.
  • Computed tomography revealed tumors within the right atrium.
  • Surgical resection of the observed masses was successfully performed.

Findings:

  • The resected masses were identified as blood cysts.
  • These blood cysts extended from the right atrium into the inferior vena cava.
  • This presentation is exceptionally rare in adult patients.

Implications:

  • This case underscores the possibility of intracardiac blood cysts persisting into adulthood.
  • The findings challenge the typical understanding of the natural history of these lesions.
  • Further consideration of surgical timing and management strategies for rare adult presentations is warranted.
