Pheochromocytomas are rare tumors arising from chromaffin cells of the adrenal medulla and extramedullary sympathetic ganglia. The incidence of asymptomatic disease is rising due to increased detection rates from widespread use of computed tomography. We describe a case of one of the largest documented pheochromocytomas resected in the United States, an 18-cm tumor in a patient who presented with exertional dyspnea, abdominal pain, constipation, weight loss, and intermittent hypertension. After biochemical and appropriate imaging workup, the patient underwent an open resection of the mass.
嗜铬细胞瘤是起源于肾上腺髓质嗜铬细胞和髓外交感神经节的罕见肿瘤。由于计算机断层扫描的广泛应用提高了检测率，无症状疾病的发病率正在上升。我们描述了一例在美国切除的有记录以来最大的嗜铬细胞瘤病例，该肿瘤大小为18厘米，患者表现为劳力性呼吸困难、腹痛、便秘、体重减轻和间歇性高血压。经过生化及适当的影像学检查后，患者接受了肿瘤的开放切除术。
