You are on board a plane and mid way through the flight. A person sitting near you became excited, restless, very talkative and maniacal following this he became very dull and pale. On examination his pupils were dilated and his body temperature elevated. On fuher examination he had ulceration of the nasal septum also. He later had convulsion. The onboard emergency kit with glucometer relieved his blood sugar to be 150 mg/dl. He also had arrhythmia. Despite resuscitative and suppoive measures he died before the plane landed. What is your diagnosis?

💡 Explanation
**Core Concept**
The underlying condition is a life-threatening emergency caused by excessive production of catecholamines, leading to hyperadrenergic state. This is characterized by symptoms such as tachycardia, hypertension, dilated pupils, and altered mental status.
**Why the Correct Answer is Right**
The symptoms described are classic for a catecholamine surge, which can be caused by a pheochromocytoma. Pheochromocytomas are rare tumors that arise from the adrenal medulla and secrete excessive amounts of catecholamines, such as epinephrine and norepinephrine. The elevated blood sugar and arrhythmia can be attributed to the catecholamine surge. The ulceration of the nasal septum is a classic sign of long-standing hypertension, which can occur due to the excessive catecholamine secretion. The convulsion can be a result of the severe hypertension.
**Why Each Wrong Option is Incorrect**
**Option A:** This is incorrect because the symptoms do not match a diagnosis of diabetic ketoacidosis (DKA), which typically presents with hyperglycemia, metabolic acidosis, and ketosis, none of which are mentioned in the scenario.
**Option B:** This is incorrect because the symptoms do not match a diagnosis of pulmonary embolism (PE), which typically presents with sudden onset of dyspnea, chest pain, and tachycardia, none of which are mentioned in the scenario.
**Option C:** This is incorrect because the symptoms do not match a diagnosis of acute coronary syndrome (ACS), which typically presents with chest pain, electrocardiographic changes, and elevated cardiac biomarkers, none of which are mentioned in the scenario.
**Clinical Pearl / High-Yield Fact**
The "rule of 3" for pheochromocytoma is a useful mnemonic to remember the classic symptoms: hypertension (3 mmHg increase), tachycardia (3 beats per minute increase), and temperature (3°C increase).
**Correct Answer: D. Pheochromocytoma**
✓ Correct Answer: A. Body stuffer syndrome
