Malignant cerebrovascular thromboembolization by phaechromocytoma

R Raghavan1, P G Ince, T J Walls

Summary

A rare adrenal tumor (phaeochromocytoma) caused malignant emboli, leading to stroke in a 56-year-old man. This unusual case highlights a unique pathway for tumor spread and vascular obstruction.

Area of Science:

  • Cardiovascular Medicine
  • Oncology
  • Nephrology

Background:

  • Malignant thromboembolism is a rare complication of cancer.
  • Adrenal phaeochromocytomas are tumors of the adrenal medulla that can secrete catecholamines.
  • Vascular invasion by tumors can lead to serious embolic events.

Observation:

  • A 56-year-old male presented with stroke symptoms.
  • Imaging revealed thromboemboli within the aortic arch and carotid arteries.
  • The source was identified as an adrenal phaeochromocytoma with extensive local invasion and metastasis.

Findings:

  • The phaeochromocytoma had invaded the inferior vena cava and metastasized to the pleural cavity.
  • Tumor emboli colonized the intimal surfaces of the aortic arch and carotid vessels.

  • This led to malignant thromboembolization causing the patient's stroke.

    • Implications:

    • This case underscores the importance of considering rare tumor origins for embolic events.
    • It highlights an unusual pattern of malignant spread from an adrenal phaeochromocytoma.
    • Early recognition and management of such cases are crucial for patient outcomes.
