摘　　要：目的研究分析腮腺Warthin瘤的多层螺旋CT影像表现,探讨64层螺旋CT对腮腺Warthin瘤的诊断价值及合理扫描方案。资料与方法回顾性分析15例经手术及组织学病理证实的腮腺Warthin瘤的CT平扫及两期增强表现。结果 15例腮腺Warthin瘤患者中7例单侧发病,8例双侧发病,总共26个病灶;位于腮腺浅叶后下部22个,其他部位4个;20个病灶呈结节状,径线范围为0.8～4cm;其中23个边界清楚,12个密度均匀,14个病灶内见囊变区,3个病灶内可见钙化。两期增强扫描中动脉期各病灶呈中度至明显强化,静脉期21例病灶密度降低,5例与动脉期相近,病灶内囊变区两期增强均未见强化。结论 64层螺旋CT对于腮腺Warthin瘤的诊断具有很强的实用性,合理的扫描方案能提高该疾病的诊断准确率。Purpose To analyze multi-slice spiral CT images of parotid Warthin tumor, and investigate its diagnostic value and make a reasonable scan protocol. Materials and Methods The plain and two-phase enhanced CT characteristics of 15 cases of Warthin tumor confirmed by surgery and histological pathology were retrospectively analyzed. Results There were total 26 lesions in 15 cases, 7 cases with lesions in unilateral side and 8 cases in bilateral sides. 22 lesions located in the superficial lobe, 4 lesions in other parts. 20 lesions were nodular,the diameters were in the range between 0.8～4cm. 23 lesions were clear boundary,12 lesions were homogeneous. Cystic areas were found in 14 lesions and calcification in 3 lesions. All lesions showed significantly enhancement in the arterial phase. The density of 21 lesions were decreased in vein phase, 5 lesions had similar density to that in the arterial phase. Cystic areas were not enhanced in both phases. Conclusion 64-slice spiral CT is useful in the diagnosis and differential diagnosis of Warthin tumor. Making a reasonable scan protocol can improve accuracy of the diagnosis and differential diagnosis.
