This study details a rare cardiac pheochromocytoma successfully removed from a 32-year-old male. Advanced imaging, including MIBG-scintigraphy, contrast-enhanced CT, and ECG-gated MRI, was crucial for diagnosis and localization.

Area of Science:

  • Cardiology
  • Oncology
  • Radiology

Background:

  • Cardiac pheochromocytoma is an exceptionally rare tumor, posing significant diagnostic challenges due to its location.
  • Accurate localization is critical for successful surgical resection and patient management.

Observation:

  • A 32-year-old male presented with symptoms suggestive of a cardiac tumor.
  • Initial unenhanced computed tomography (CT) failed to identify the lesion.
  • Metaiodobenzylguanidine (MIBG)-scintigraphy provided initial localization clues.

Findings:

  • Dynamic contrast-enhanced CT of the chest, performed under alpha and beta blockade, was essential for comprehensive tumor characterization.
  • Electrocardiogram (ECG)-gated magnetic resonance imaging (MRI) provided detailed anatomical information, complementing CT findings.

  • The cardiac pheochromocytoma was successfully localized and subsequently resected.

    • Implications:

    • This case highlights the importance of multi-modal imaging in diagnosing rare cardiac tumors.
    • Pharmacological blockade during contrast-enhanced CT is vital for accurate pheochromocytoma imaging.
    • Successful surgical outcomes are achievable with precise pre-operative localization.
