A misdiagnosed cardiac tumor was revealed as high-grade lymphoma through advanced transesophageal echocardiography. This case highlights the importance of comprehensive echocardiography in diagnosing cardiac masses and their impact.

Area of Science:

  • Cardiology
  • Oncology
  • Medical Imaging

Background:

  • Initial diagnosis suggested benign arrhythmia and intracardiac tumor based on transthoracic echocardiography and initial transesophageal echocardiogram.
  • Distinguishing benign cardiac masses from malignant tumors can be challenging with initial imaging modalities.

Observation:

  • A patient presented with symptoms initially attributed to benign cardiac conditions.
  • A subsequent, comprehensive transesophageal echocardiogram revealed extensive intra- and extracardiac masses with malignant features.
  • Masses were observed to compress mediastinal vascular structures.

Findings:

  • Peripheral biopsy confirmed a diagnosis of high-grade lymphoma.
  • Comprehensive transesophageal echocardiography accurately defined the extent and location of the cardiac masses.

  • Malignant features were identified, contrasting with typical myxoma characteristics.

    • Implications:

    • Transesophageal echocardiography is crucial for detailed assessment of cardiac mass lesions and their physiological impact.
    • Comprehensive echocardiographic evaluation, including spectral Doppler, aids in differentiating benign from malignant cardiac tumors.
    • Early and accurate diagnosis through advanced imaging is vital for effective lymphoma treatment.
