What is the Difference Between Conn’s Syndrome and Pheochromocytoma?

🆚 Go to Comparative Table 🆚

Conn's Syndrome and Pheochromocytoma are two distinct medical conditions that affect the adrenal glands. The main differences between the two are:

  1. Hormone production: Conn's Syndrome is due to the overproduction of aldosterone, which controls sodium and potassium levels in the blood. Pheochromocytoma, on the other hand, is a condition due to the overproduction of adrenaline and noradrenaline, which control many body functions, such as heart rate, blood pressure, and blood sugar.
  2. Affected adrenal region: Conn's Syndrome mainly affects the adrenal cortex, while pheochromocytoma mainly affects the adrenal medulla.
  3. Tumor type: Conn's Syndrome is caused by an aldosteronoma, an adrenal tumor that makes excess amounts of aldosterone. Pheochromocytoma is a tumor that develops in the center of the adrenal gland, usually due to a noncancerous tumor.
  4. Symptoms: The symptoms of Conn's Syndrome include hypertension, headache, weakness, muscle cramps, and temporary paralysis. Pheochromocytoma symptoms include hypertension, headache, palpitations, sweating, and panic attacks.
  5. Diagnosis: Both conditions can be diagnosed through blood tests and imaging tests, such as CT scans, X-rays, MRI scans, and genetic testing.
  6. Treatment: The primary treatment for Conn's Syndrome is medications like spironolactone or eplerenone, which block the effects of aldosterone, removing the problematic adrenal gland surgically, and lifestyle changes. Pheochromocytoma is usually treated by surgically removing the tumor or adrenal glands.

In summary, Conn's Syndrome is characterized by the overproduction of aldosterone and mainly affects the adrenal cortex, while pheochromocytoma is characterized by the overproduction of adrenaline and noradrenaline and mainly affects the adrenal medulla. The symptoms, diagnostic methods, and treatments for the two conditions also differ.

    Here is a table comparing Conn's Syndrome and Pheochromocytoma:

    Feature Conn's Syndrome Pheochromocytoma
    Definition A condition due to the overproduction of aldosterone, which controls sodium and potassium levels in the blood. A condition due to the overproduction of adrenaline and noradrenaline, which control many body functions such as heart rate, blood pressure, and blood sugar.
    Affected Area Mainly affects the adrenal cortex. Mainly affects the adrenal medulla.
    Hormone Excess production of aldosterone. Excess production of catecholamines (adrenaline and noradrenaline).
    Symptoms Elevated blood pressure, fluid imbalance, and low potassium levels. Headaches, sweating, palpitations, racing heart, flushing, panic attacks, and potentially severe blood pressure elevations.
    Diagnosis Blood tests and imaging tests. Blood tests and imaging tests.
    Treatment Surgically removing the tumor or adrenal glands. Surgically removing the tumor or adrenal glands.

    Both conditions are due to adrenal gland tumors and can result in complications.
