目的评估CT检查对腮腺肿瘤鉴别诊断的价值。方法回顾性分析了经病理证实的48例腮腺肿瘤患者CT表现,并同病理所见进行对照研究,采用双盲阅片评估CT对腮腺良、恶性肿瘤的鉴别诊断价值。结果18例良性肿瘤,密度均匀、边界清楚12例,密度不均、部分境界不清6例。30例恶性肿瘤,密度不均匀、边界模糊24例;密度较均匀,境界清楚6例。48例肿瘤的CT图像中均未见面神经显示。双盲阅片结果表明:CT对78.9%的腮腺肿块能正常定性(炎性反应,良或恶性肿瘤),但不能确认其组织学类型。结论CT能鉴别大多数的良、恶性肿瘤,但不能确定其组织学类型。
Objective To assess the value of CT in the differential diagnosis of parotid tumors. Methods The CT findings of 48 parotid gland tumors confirmed by pathology were retrospectively analyzed. The results of pathological examination were compared with those of pathological findings. The differential diagnosis of benign and malignant parotid tumors was evaluated by double blind reading. Results 18 cases of benign tumors, uniform density, clear border in 12 cases, uneven density, some of the unknown realm in 6 cases. 30 cases of malignant tumor, uneven density, fuzzy boundaries in 24 cases; density is more uniform, the state clearly in 6 cases. 48 cases of tumor CT images showed no facial nerve. Double-blind reading results show that: CT of 78.9% of parotid masses can be normal qualitative (inflammatory response, good or malignant tumor), but can not confirm the histological type. Conclusion CT can identify most of the benign and malignant tumors, but can not determine the histological type.
