摘　　要：患者女,51岁,发现右侧耳下无痛性包块4年,近一年进行性增大;颈部视诊右侧腮腺处稍有隆起,周围皮肤无红肿、麻木,无皮肤表面溃烂,右侧腮腺区可触及一3 cm × 3 cm × 3 cm肿物,边界尚清,质韧,活动可,与周围组织无粘连;CT提示:右侧腮腺浅叶后下极见一椭圆形稍低密度影,边界尚清,大小约2.2 cm × 1.8 cm,平扫CT值为35 HU;增强扫描成不均匀渐进性、延迟强化,增强双期CT值分别为99 HU、123 HU;CT诊断:右侧腮腺浅叶后下极占位,多考虑肿瘤性病变(多形性腺瘤可能)。患者全麻下行右侧腮腺浅叶肿物切除术,术后病理诊断:(右侧腮腺)嗜酸性细胞腺瘤,局部瘤细胞增生活跃。A 51-year-old female patient had a right subauricular painless mass for 4 years and progressive enlargement in the past year. Visual examination of the neck showed a slight eminence in the right parotid gland, no swelling, numbness or ulceration on the surrounding skin, and a 3 cm × 3 cm × 3 cm mass could be detected in the right parotid gland area, with clear boundary, tough quality and easy movement, and no adhesion to the surrounding tissue. CT showed that there was a slightly low-density oval shadow with clear boundary at the posterior lower pole of the superficial lobe of the right parotid gland, with a size of about 2.2 cm × 1.8 cm. Plain CT value was 35 HU. The en-hanced scan showed uneven progressive enhancement and delayed enhancement, and the two-phase enhanced CT values were 99 HU and 123 HU, respectively. CT diagnosis: The posterior inferior pole of the superficial lobe of the right parotid gland was occupied, and neoplastic lesions (pleomorphic adenoma was a possibility) were considered. The patient underwent resection of the superficial lobe mass of the right parotid gland under general anesthesia. The postoperative patho-logical diagnosis was eosinophilic adenoma of the right parotid gland, with active local tumor cell proliferation.
