Phaeochromocytoma

Also called Pheochromocytoma or Adrenal tumour

A phaeochromocytoma is a rare tumour that grows in the adrenal glands, which sit on top of the kidneys. It makes too much adrenaline and similar hormones, which can cause high blood pressure and attacks of headache, sweating and a pounding heartbeat. Most are not cancer. Some are linked to inherited conditions.

What it is

Medicines are given first to control blood pressure, then the tumour is usually removed with surgery.

Long-term follow-up and sometimes genetic testing are recommended, as it can come back or run in families.

Common signs

  • High blood pressure, sometimes hard to control
  • Attacks of headache, sweating and a pounding heartbeat
  • Feeling anxious or shaky
  • Looking pale
  • Feeling sick

How it is usually diagnosed

  • Blood or urine tests for metanephrines
  • CT or MRI scan
  • Sometimes a special nuclear medicine scan

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Blood and urine test results
  • Scan reports
  • Endocrinology and surgery letters
  • Genetic test results

Questions to ask your doctor

  • Is the tumour cancerous?
  • How will my blood pressure be controlled before surgery?
  • Should my family have genetic testing?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A severe headache with chest pain, a very fast heartbeat or confusion: call 112
