摘 要:目的分析头部和气管腺样囊性癌(ACC)的临床表现和影像学征象。方法对32例经病理证实的腺样囊性癌进行回顾性分析。其中男20例,女12例,年龄范围21~73岁,平均年龄46.2岁。结果ACC具有浸润性生长的特点。CT有利于显示骨质破坏。MRI可显示肿瘤边界及其侵犯范围。T2WI信号可反映组织类型,提示预后。结论ACC缺乏特异性,确诊靠病理学诊断。本病具有明显沿神经扩展、少见淋巴转移的特点。Purpose To evaluate the clinical findings and imaging characteristics of adenoid cystic carcinomas(ACC). Methods The case histories of 32 patients with ACC proven at histologic examination were retrospectively reviewed. There were twenty male patients and twelve female patients aged 21-73 with an average of 46.2. Results ACC appeared as poorly defined neoplasms with infiltrative margins. Computed tomography was useful to demonstrate bone destruction. Magnetic resonance imaging depicted the lesion and its extension in its entirety. Signal intensity on T 2 weighted MR images correlated with the degree of cellularity of the lesion,and might help determine the prognosis of the lesion. Conclusion ACC imaging is lack of specificity, and biopsy remains mandatory but tendency to spread through perineural spaces and few lymphatic metastasis are the common characteristics of ACC. Imaging examination defines the tumor and its extension and enables effective therapeutic planning and follow up evaluation.
