Pheochromocytoma diagnosis relies on clinical, biochemical, and imaging methods. Early detection and surgical treatment are crucial for preventing severe cardiovascular events and associated neoplastic syndromes.

Area of Science:

  • Endocrinology
  • Oncology
  • Radiology

Context:

  • Pheochromocytoma is a rare neuroendocrine tumor originating from chromaffin cells.
  • Accurate diagnosis and management are essential due to potential life-threatening complications.

Purpose:

  • To review the diagnostic and therapeutic strategies for pheochromocytoma at Hospital das Clínicas, FMUSP.
  • To highlight the utility of various biochemical and imaging modalities.

Summary:

  • Discusses clinical, biochemical (plasma/urinary metanephrines, catecholamines), and topographic (MRI) diagnostic approaches.
  • Emphasizes the importance of stimulation/suppression tests and drug withdrawal for accurate biochemical assessment.
  • Outlines surgical treatment preceded by clinical management as the standard of care.

Impact:

  • Highlights the diagnostic value of both novel and conventional biochemical tests.
  • Underscores the high sensitivity of MRI for tumor localization.
  • Stresses the critical role of timely diagnosis in preventing cardiovascular morbidity and mortality.
