腮腺病变的CT征象探讨

Research into the CT signs of parotidean lesions

目的总结50例腮腺病变的CT表现,以期进一步提高对腮腺病变的认识。方法对我院手术病理证实的腮腺肿瘤50例,其中炎性病变6例(包括结核2例);恶性肿瘤18例,良性肿瘤26例,均经增强前后CT扫描。结果腮腺良恶性病变的CT影像学表现各有特点,良性病变边界清,可伴钙化,恶性病变呈浸润性生长,可伴骨质破坏。CT扫描可显示病变形态、大小、位置,同时也可显示周围结构的继发改变。结论CT检查在腮腺病变诊断中具有重要价值。

Objective To elevate the cognition of parotidean lesions by summarizing their CT findings. Methods Fifty patients with surgically and pathologically proved parotidean lesions which comprised 6 cases of inflammatory lesions（2 tuberculosis）, 18 cases of malignant tumors and 26 cases of benign tumors underwent CT scans of the head and neck without and with contrast enhancement. Results The study demonstrated that, the CT findings of benign and malignant parotidean lesions were obviously different, for example, most benign lesions had clear border or associated with calcification, whereas most malignant lesions appeared as infiltrating growth or associated with bony destruction. CT scanning could reveal the shape, size and site of varied parotidean lesions as well as the changes of surrounding structures. Conclusion CT examination has important value in the diagnosis of parotidean lesions.
