摘要

摘要: 目的:分析腮腺腺泡细胞癌的MRI图像特点,进一步提高该病在MRI上的诊断水平。方法:回顾性分析11例经手术病理确诊的腮腺腺泡细胞癌患者的MRI表现及临床特点。MRI分析内容包括肿瘤数目、部位、大小、形态、边界、包膜、信号特点、增强扫描病灶强化特点、颈部淋巴结肿大情况等。临床分析包括患者的年龄、性别及随访情况等。结果:11例患者均单侧腮腺单发,共11个肿瘤,右侧腮腺7个,左侧腮腺4个;肿瘤平均最大长径(2.66±0.99)cm;7个肿瘤有分叶,4个呈类圆形;8例未见假包膜,3例显示不完整假包膜。T₁WI:肿瘤以等高信号为主;T₂WI:肿瘤以高信号为主。增强扫描,明显均匀或不均匀强化。结论:当腮腺内肿瘤未见包膜(或包膜显示不完整)、有分叶、内有小囊变以及明显强化时,可能提示腮腺腺泡细胞癌,确诊仍需结合临床病理检查。

Abstract: Objective:To analyze the MR imaging findins of acinic cell carcinoma(ACC) in parotid gland and develop the diagnosis of this disease. Method:The MR imaging fearures of 11 patients with pathologically proved ACC were retrospectively analyzed. MR imagings were analyzed in relation to the follow:amount, location, size, shape, margin, pseudocapsule, MR signal intensity and enhanced pattern and the cervical lymphadenopathy. The clinical analysis on patients included age, sex, and follow-up.Result:There were 11 patients,7 lesions was located in the right parotid gland and 4 lesions was located in the left parotid gland; the average maximum diameter was (2.66±0.99)cm; 7 lesions showed lobulated,and 4 lesions showed round; 8 lesions had no pseudocapsules and 3 lesions had incomplete pseudocapsule. All lesions showed homogeneous or heterogeneous isointense and slight hyperintense on T₁WI and T₂WI. On post contrast images, the tumor parenchyma ingredients showed remarkable enhancement in all lesions.Conclusion:The MR imaging of ACC in the parotid gland don't have specific features, but when the tumor of the parotid gland showed no pseudocapsule (or showed incomplete pseudocapsule), lobulate, small cysitc and remarkable enhancement, it may indicate ACC, and the correct diagnosis depends on clinical pathology.
