Overview

Head, neck, chest, and abdominal MRI may be helpful in the diagnosis of pheochromocytoma.

Key MRI Findings in Pheochromocytoma

Key MRI findings in pheochromocytoma are:[1]

  • T1-weighted
  • T2-weighted
  • T1 with gadolinium contrast[4]
    • Heterogenous enhancement is prolonged, persisting for as long as 50 minutes.
  • Increased vascularity and may be bilateral and hemorrhagic changes.
  • T2 weighted MRI of the head, neck, and chest, and abdomen can help localize the tumor.
