目的:探讨CT对腮腺多形性腺瘤的诊断价值。方法:分析20例经手术病理证实的腮腺多形性腺瘤患者的CT平扫及其中9例增强扫描,总结其CT表现。结果:20例腮腺多形性腺瘤病例中,14例圆形或椭圆形,6例呈多结节分叶形,密度高于正常腮腺组织;18例肿物边缘清楚,密度均匀或不均匀,可伴有囊变及钙化;2例为术后复发,边界不清,可见大片坏死区。结论:CT对于腮腺多形性腺瘤的定位及定性诊断具有重要价值。
Objective: To investigate the diagnostic value of CT on parotid pleomorphic adenoma. Methods: Twenty cases of parotid pleomorphic adenoma confirmed by surgery and pathology were analyzed by CT scan and nine cases of enhancement scan. The CT findings were summarized. Results: Of 20 cases of parotid pleomorphic adenoma, 14 cases were round or oval, 6 cases were multi-nodular lobes and their density was higher than that of normal parotid gland. Eighteen tumors had clear margin and even density, Can be associated with cystic and calcification; 2 cases of postoperative recurrence, the border is unclear, showing large areas of necrosis. Conclusion: CT is of great value for the localization and qualitative diagnosis of parotid pleomorphic adenoma.
