What distinguishes a panic attack from pheochromocytoma?

• A. Panic attacks are chronic.
• B. Pheochromocytoma has higher and longer lasting blood pressure.
• C. Panic attacks lack physical symptoms.
• D. Pheochromocytoma is unrelated to blood pressure changes.

Answer: (B)

The distinguishing factor that supports the choice regarding pheochromocytoma is the characteristic of having higher and longer-lasting blood pressure associated with this condition. Pheochromocytoma is a tumor of the adrenal glands that secretes catecholamines, leading to episodes of elevated blood pressure, palpitations, sweating, and other symptoms. These hypertensive episodes can persist for extended periods and can occur spontaneously or be triggered by various factors.

In contrast, panic attacks typically involve sudden episodes of intense fear or discomfort that peak within minutes and can include physical symptoms such as increased heart rate, shortness of breath, or dizziness, but they do not cause sustained increases in blood pressure like pheochromocytoma does. Understanding this distinction is critical for differentiating between these two conditions in a clinical setting.
