Pheochromocytoma | USMLE Step 2 CK | High-Yield Internal Medicine & Endocrinology Review This high-yield video on Pheochromocytoma is tailored for students preparing for the USMLE Step 2 CK, focusing on the clinical presentation, diagnosis, and management of this rare but life-threatening catecholamine-secreting tumor. Originating from chromaffin cells of the adrenal medulla, pheochromocytoma causes paroxysmal or sustained hypertension due to excess production of epinephrine, norepinephrine, and sometimes dopamine. Step 2 CK frequently features classic vignettes where rapid recognition is key to preventing complications like hypertensive crisis, arrhythmias, or stroke. In this lecture, you'll learn how to recognize hallmark symptoms using the “Rule of 5 P’s”: Paroxysmal hypertension, Palpitations, Pallor, Perspiration, and Pain (headache). We explain the importance of biochemical testing, starting with plasma free metanephrines or 24-hour urinary metanephrines and catecholamines, followed by imaging with CT/MRI of the adrenal glands or MIBG scan for extra-adrenal tumors. You’ll also understand how to differentiate pheochromocytoma from other causes of secondary hypertension such as hyperaldosteronism, renal artery stenosis, and Cushing’s syndrome, and how to identify syndromic associations like MEN 2A/2B, NF1, and VHL. Preoperative preparation is essential: alpha-blockade with phenoxybenzamine is initiated before any beta-blocker to avoid unopposed alpha stimulation, which can trigger a hypertensive crisis. The video walks you through the correct medical sequence and surgical planning to avoid intraoperative complications. By the end of this video, you’ll be fully prepared to approach any USMLE-style question or clinical case involving pheochromocytoma, confidently interpreting hormonal tests, managing hypertension, and selecting the safest treatment approach. #Pheochromocytoma #USMLEStep2CK #Catecholamines #Metanephrines #Phenoxybenzamine #AdrenalTumor #Hypertension #MEN2A #MEN2B #VHL #NF1 #AdrenalMedulla #USMLEBuzzwords #InternalMedicineReview #Step2Prep #WhiteboardMedicine #DrGBhanuPrakash #SurgicalPrep #MIBGScan #NBMEReview #USMLE2025 #SecondaryHypertension #AlphaBlockade #BetaBlockerPrecaution #ConceptualMedicine #MedicalConcepts #NEETPGPrep #FMGE2025 #USMLE2025 #ClinicalMedicine #MBBSConcepts #NextExamPrep #MedSchoolMadeEasy #MedStudentLife #HighYieldMedicine #PathophysiologySimplified #LearnMedicineFast #VisualMedicine #MedicalMnemonics #CrackNEETPG #USMLEStep1Prep #MedEducationRevolution #MBBSShorts #DoctorInTheMaking
