目的:评价CT对腮腺良恶性病变的诊断价值。方法:回顾性分析经手术病理证实的47例腮腺病变的CT表现。良性36例,恶性11例。CT平扫46例,增强扫描38例。结果:良性肿瘤无侵袭性,边缘清楚,密度均匀或不均匀,有钙化、囊变、坏死;炎性肿块者,灶周可有磨玻璃影,呈晕征;恶性肿瘤具有不同程度的侵袭性,多呈分叶状,不规则或浸润性生长,边缘不清。CT对腮腺病变定位准确率100% ,而对良恶性定性诊断符合率分别为恶性组72.7% ,良性组80.6% 。结论:CT对腮腺病变定位、定性诊断,特别是区别良恶性病变方面具有较高的价值
Objective: To evaluate the diagnostic value of CT in benign and malignant parotid lesions. Methods: The CT findings of 47 parotid lesions confirmed by surgery and pathology were analyzed retrospectively. 36 cases of benign, 11 cases of malignant. CT scan in 46 cases, enhanced scanning in 38 cases. Results: benign tumor without invasive, clear edge, uniform density or uneven, with calcification, cystic degeneration, necrosis; inflammatory mass who can have the glass around the flesh, was halo sign; malignant tumor with varying degrees of invasiveness , Mostly lobulated, irregular or infiltrative growth, the edge is unclear. CT parotid lesions localization accuracy of 100%, while the qualitative diagnosis of benign and malignant were 72.7%, 80.6% of the benign group. Conclusion: CT has a high value for localization and qualitative diagnosis of parotid gland lesions, especially for benign and malignant lesions
