Pheochromocytomas are rare tumors arising from chromaffin cells of the sympathoadrenal system and 85% of them are located in the adrenal medulla. Malignant pheochromocytomas account for 10% of all pheochromocytomas. Since clinical, biochemical and histopathological features can not reliably distinguish malignant from benign tumors, malignancy is established in the presence of distant metastases. Although in some cases, metastases may develop during follow-up, most of these tumors have metastatic disease at initial presentation. In this case report, detection of distant metastases and recurrence developed during follow-up with 18-flouro-deoxyglucose positron emission tomography/computed tomography (FDG PET/CT) in a patient with malignant pheochromocytoma was presented.

嗜铬细胞瘤是起源于交感肾上腺系统嗜铬细胞的罕见肿瘤，其中85%位于肾上腺髓质。恶性嗜铬细胞瘤占所有嗜铬细胞瘤的10%。由于临床、生化和组织病理学特征无法可靠地区分恶性肿瘤和良性肿瘤，因此在存在远处转移的情况下可确诊为恶性。尽管在某些情况下，转移可能在随访期间出现，但这些肿瘤大多数在初次就诊时就已发生转移。在本病例报告中，介绍了一名恶性嗜铬细胞瘤患者在随访期间通过18-氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（FDG PET/CT）检测到远处转移和复发的情况。
