Unilateral hypermetabolic lesion of parotid gland demonstrated on PET/CT imaging may originate from a large spectrum of benign or malignant processes, such as adenoma, Warthin's tumor, oncocytic neoplasm, lymphoma, and primary or secondary malignancy of the gland. Bilateral and multifocal parotid gland disease is less common but possible because of the known characteristics of Warthin's tumors. The authors present such a case that was incidentally documented during PET/CT evaluation of solitary pulmonary nodule.
PET/CT 影像显示单侧腮腺高代谢性病变可能源于广泛的良性或恶性病变，如腺瘤、Warthin 瘤、嗜酸细胞瘤、淋巴瘤以及腺体的原发性或继发性恶性肿瘤。双侧和多灶性腮腺疾病虽不太常见，但由于已知的 Warthin 瘤特征，也有可能发生。作者介绍了这样一个病例，在孤立性肺结节的 PET/CT 评估过程中偶然记录到该病例。
