摘要
目的：探讨CT检查对腮腺区肿瘤的定位、定性诊断的价值。材料与方法：分析16例经手术或穿刺活检病理证实的腮腺区肿瘤的CT表现。着重观察病变的位置、边缘、密度。及对周围结构的侵犯情况。结果：腮腺良性肿瘤9例，CT显示圆形或椭圆形稍高密度灶，密度均匀，边界清楚，无周围侵犯；腮腺恶性肿瘤7例，显示边缘不规则肿块，密度不均，边界不清；5例有周围结构侵犯。结论：CT对发现腮腺区肿瘤和肿瘤深、浅叶的定位较为可靠；对鉴别肿瘤的良、恶性有较高价值。
To assess the clinical value of tumor -- localizing and differenhal diagnosis in the area of p^hdwith ac exalnhation. Meterial and Method: To analyse CT scan of paIDtid tUInor for 16 cases colnfirmed b}, operationand biopsy. To observe location, margin, density and ambient stmctUre invasion Of the tUmor. Result: 9 cases ofbenign PaIDhd ~r delnonSllated the round or elliphcal soft-tissue mass, with homogeneous density, well-defined~, and without ambient stl'Uc~ invasion; 7 cases of malignant PaIDhd tUInor showed the irregUlar mass, with^defined malgin and bete^s denSity; with 5 cases shown ambient instructure invasion. Conclusion: CT isreliable in deteCting and ~hating the posihon of superficial or deep lobe of fetid tUmor, and has a major value indiswishing the benign ho malignant nato Of ~d ~.
