【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 MRI features of parotid acinar cell carcinoma and to improve the diagnostic level of the disease on MRI. Methods: the MRI findings and clinical features of 11 patients with parotid acinar cell carcinoma confirmed by operation and pathology were retrospectively analyzed. Enhanced scanning focus enhancement features, cervical lymph node enlargement and so on. Clinical analysis included age, sex, and follow-up. Results all the 11 cases were unilateral parotid gland with 11 tumors, 7 in the right parotid gland and 4 in the left parotid gland. The mean maximum length of tumor was (2.66 卤0.99) cm, 7 tumors were lobulated, and 8 cases had no pseudocapsule. 3 cases showed incomplete pseudocapsule. T1WI: the tumor was characterized by isobaric signal and hyperintense. Enhanced scanning, obviously uniform or uneven enhancement. Conclusion: the diagnosis of parotid acinar cell carcinoma should be combined with clinicopathological examination when there is no capsule (or incomplete appearance of capsule), lobulation, small cystic degeneration and obvious enhancement of parotid gland acinar cell carcinoma.
