Oncocytoma of the salivary glands is a rare tumor that usually follows a benign course and, in most cases, can be cured by surgical resection. The authors report a rare case of multiple bilateral parotid oncocytomas that presented clinically with two palpable parotid masses. Both CT and MRI scans demonstrated multiple masses in each parotid gland. The tumors exhibited intense uptake and prolonged retention of Tc-99m pertechnetate. The diagnosis was confirmed by fine needle aspiration. Sialoscintigraphy is a simple and noninvasive procedure that can usually separate benign entities like Warthin tumor and oncocytoma of the salivary glands from malignant tumors, and significantly affect the course of treatment.
涎腺嗜酸性细胞瘤是一种罕见肿瘤，通常呈良性病程，在大多数情况下，可通过手术切除治愈。作者报告了1例罕见的双侧腮腺多发性嗜酸性细胞瘤病例，临床上表现为双侧可触及的腮腺肿块。CT和MRI扫描均显示双侧腮腺内有多个肿块。肿瘤对99m锝高锝酸盐摄取强烈且滞留时间延长。通过细针穿刺确诊。唾液腺闪烁显像术是一种简单且无创的检查方法，通常能够将沃辛瘤和涎腺嗜酸性细胞瘤等良性病变与恶性肿瘤区分开来，并显著影响治疗进程。
