摘　　要：目的:探讨螺旋CT在腮腺肿瘤诊断方面的价值。方法:回顾性分析81例腮腺病变的资料,将CT表现与手术病理结果进行对比分析,进而分析不同病理特征腮腺肿瘤的CT表现特点。结果:良性肿瘤表现形态规则,边界清晰;多形性腺瘤多呈进行性、延迟强化;腺淋巴瘤强化方式表现为"快进快出";基底细胞腺瘤肿瘤实性部分动脉期强化显著,静脉期持续强化。恶性肿瘤多表现形态不规则、边界不清,并伴邻近组织浸润。结论:螺旋CT对腮腺肿瘤的诊断及鉴别诊断具有重要参考价值。Objective To exploration of diagnostic values of the spiral CT in Parotid tumors. Methods CT manifestations and pathology results were retrospectively analyzed in 81 cases of parotid gland lesion. In con- trast to pathological findings after surgery,then analyzes the different features of CT manifestation in different pathological features of parotid gland tumors. Results Benign tumors in 63 cases showed regular shape and clear boundary. Pleomorphic adenomas tended to progressive and delayed enhancement. Parotid adenolympho- mas enhancement approached to the ＂rapid filling and quick washout ＂ feature. Solid part of basal cell adeno- mas enhanced remarkably in the arterial phase and strengthened in the venous phase. Malignant tumors in 11 cases showed irregular shape, ill-defined boundary and infiltrating into adjacent tissue. Conclusion Spiral CT scanning has important reference value in the diagnosis and differential diagnosis of parotid gland tumors.
