腮腺造影对定性诊断的价值

THE VALUE OF SIALOGAPHY IN THE DIAGNOSIS OF PAROTID TUMOR

本文报道经手术病理确诊的腮腺良性肿瘤41例,恶性肿瘤25例的造影检查结果。腮腺肿瘤X线征、良性:充盈缺损,边缘清楚;分支导管无破坏、呈抱球状或弧形变:无碘油存留。恶性:充盈缺损,边缘模糊;分支导管破坏;可有碘油池,大多数腮腺肿瘤可以用腮腺造影检查确诊。本组良性肿瘤显影符合率为87.8％(36/41),恶性肿瘤为88％(22/25),略高于国内文献。造影检查对良恶性的定性有较大价值。我们认为造影立体照片对诊断是有用的。

The sialography of 66 surgically and pathologically proved cases ofparotid tumor (benign 41, malignant 25) were analyzed. The X-ray signs of parotid tumors were as follows Benign: filling defect with clear edge, encased by curved undestructed ducts(ball-embraced sign), no contrast retention Malignant: filling defect with hazy edge, bifurcated ducts destructed, with or without oil pools. A correct diagnosis can usually be made based on sialography examination in the majority of cases: in 36 cases(87.8%) of benign tumor and 22 cases (88%) of malignant, turner These figures are higher than those reported in the literature. The results showed tkhat sialography was valuable in the diagnosis, of parotid tumor. We think that stereoentgenography is helpful for diagnosis.
