Introduction: Hemorrhagic suprarenal masses presenting with hypertensive emergency pose a significant diagnostic challenge, particularly when biochemical and radiological findings are inconclusive. The clinical presentation may mimic catecholamine-secreting tumors, necessitating consideration of a broad differential diagnosis, including pheochromocytoma, adrenocortical carcinoma, retroperitoneal hemorrhage, and hematological-related extramedullary lesions. Accurate diagnosis is essential, as management strategies differ significantly. Case: We report a 48-year-old male smoker with no known prior medical illness who presented with sudden left-sided chest pain radiating to the epigastrium, associated with vomiting. On arrival, he was markedly hypertensive (207/131 mmHg). He reported a 1-year history of paroxysmal palpitations, headaches, migraines, and intermittent diaphoresis. Computed tomography angiography excluded aortic dissection but demonstrated a left retroperitoneal hemorrhage with non-visualization of the adrenal gland, suggestive of adrenal or tumor-related hemorrhage. He was initially managed empirically as a pheochromocytoma while undergoing biochemical evaluation; however, urinary metanephrines were only mildly elevated. Repeat imaging demonstrated interval enlargement of a non-enhancing suprarenal mass, raising concern for tumor-related hemorrhage. Subsequent ultrasonography, however, favored a liquefied hematoma, and percutaneous drainage yielded 750 mL of sanguineous fluid, resulting in marked clinical improvement. Notably, an elevated hematocrit prompted further evaluation for erythrocytosis. Subsequent testing confirmed JAK2 mutation-positive polycythemia rubra vera, providing a unifying explanation for both the erythrocytosis and spontaneous adrenal hemorrhage. The patient was commenced on hydroxyurea and referred for hematology follow-up. Conclusion Adrenal hemorrhage may closely mimic pheochromocytoma in hypertensive emergencies. A systematic, multidisciplinary approach integrating clinical, biochemical, and imaging findings is essential to avoid misdiagnosis and guide appropriate management, particularly in patients with underlying hematological disorders.
