Which of the following symptoms is NOT associated with a Pheochromocytoma?

Pheochromocytoma is a tumor of the adrenal glands that produces excessive catecholamines, leading to a variety of symptoms primarily associated with increased sympathetic nervous system activity. Common symptoms include elevated blood pressure, heart palpitations, and potentially papilledema due to secondary effects of chronic hypertension.

Elevated blood pressure is a hallmark of pheochromocytomas, often presenting as episodes of paroxysmal hypertension. Heart palpitations also occur due to the increased levels of catecholamines, which can stimulate the heart and lead to arrhythmias.

Papilledema can develop as a result of prolonged hypertension, affecting the blood flow to the optic nerve and causing swelling of the optic disc.

Fatigue, while it is a common symptom in many conditions, is not specifically associated with pheochromocytoma. Instead, the more characteristic symptoms of this condition are tied to its effects on cardiovascular function and the fight-or-flight response, which do not prominently include fatigue. Thus, fatigue does not align with the classic clinical presentation expected in patients suffering from pheochromocytoma.
