Overview

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

CT scan

• Abdominal, head, neck, and chest CT scans may be helpful in the diagnosis of pheochromocytoma.
• Radiological evaluation should follow biochemical lab tests to locate site of the tumor.
• The following findings may be observed on CT scan:
  • Adrenal mass
  • Extra-adrenal mass- most commonly in superior and inferior abdominal paraaortic areas, the urinary bladder, thorax, head, neck and pelvis.
• In patients with the multiple endocrine neoplasia type 2 (MEN2) syndrome, CT may miss the tumors.
