Pheochromocytoma, a type of neuroendocrine tumor, can cause numerous symptoms and signs similar to those of other clinical conditions, with the classic triad being palpitations, headache, and diaphoresis. Patients with pheochromocytoma can present with various cardiac complications, including myocarditis, acute coronary syndromes, cardiomyopathy, heart failure, and arrhythmias. Here we report a case of pheochromocytoma that first presented with bidirectional ventricular tachycardia. The patient was initially diagnosed with acute viral myocarditis and was treated accordingly. A pheochromocytoma crisis with severe blood pressure fluctuation occurred after glucocorticoid administration, leading to further diagnostic work-up, which eventually revealed the adrenal pheochromocytoma.
嗜铬细胞瘤是一种神经内分泌肿瘤，可引起许多与其他临床病症相似的症状和体征，典型三联征为心悸、头痛和多汗。嗜铬细胞瘤患者可出现各种心脏并发症，包括心肌炎、急性冠脉综合征、心肌病、心力衰竭和心律失常。在此，我们报告一例最初表现为双向室性心动过速的嗜铬细胞瘤病例。该患者最初被诊断为急性病毒性心肌炎并接受了相应治疗。给予糖皮质激素后发生了伴有严重血压波动的嗜铬细胞瘤危象，促使进一步的诊断检查，最终发现了肾上腺嗜铬细胞瘤。
