摘　　要：目的:探讨多层螺旋CT(Multi-slice Spiral Computed Tomography,MSCT)对腮腺深叶肿瘤的诊断价值。方法:回顾性研究分析111例经手术及病理证实的腮腺深叶肿瘤患者的临床资料与MSCT影像学表现,探讨MSCT的辅助诊断价值。结果:(1)腮腺深叶肿瘤111例患者中良性肿瘤82例、恶性肿瘤29例;(2)MSCT平扫描:良性肿瘤病例组病灶形态规则75例(91.5%)、边界清楚69例(84.1%)、伴钙化灶5例(6.1%),恶性肿瘤病例组病灶形态规则13例(44.8%)、边界清楚13例(44.8%)、伴有钙化灶6例(20.7%);两组病例在肿瘤形态(χ^(2)=26.075,P<0.05)、边界(χ^(2)=17.6,P<0.05)、钙化灶(χ^(2)=3.606,P<0.05),差异具有统计学意义;两组病例在肿瘤的囊变、对周围骨质破坏情况、边缘强化差异无统计学意义(P>0.05);(3)MSCT增强扫描:多形性腺瘤呈渐进性强化,Warthin瘤增强扫描后动静脉期呈“快进快出”强化成像;基底细胞腺瘤以显著持续强化为特点;恶性肿瘤组除黏液表皮样癌表现为“快进快出”的强化特点,其他恶性肿瘤病例多数以持续性强化为特点。结论:MSCT在腮腺深叶良恶性肿瘤诊断中具有重要作用,其中结合增强扫描可提高对疾病诊断的准确率。Objective:To evaluate the value of multi-slice spiral CT in the diagnosis of parotid deep lobe tumor.Methods:The clinical data and MSCT findings of 111cases of parotid deep lobe tumors which were diagnosed by clinical operation and pathology were analyzed retrospectively,and the value of MSCT in auxiliary diagnosis was discussed.Results:(1)Among the 111 patients with parotid deep lobe tumors,there were 82 benign tumors and 29 malignant tumors;(2)MSCT scan:75 cases(91.5%)with regular lesions,69 cases(84.1%)with clear bo-undaries,5 cases(6.1%)with calcification in benign tumor group,13 cases(44.8%)with clear boundary and 6 cases(20.7%)with calcification in malignant group.There were significant differences between the two groups in tumor morphology(χ^(2)=26.075,P<0.05),boundary(χ^(2)=17.6,P<0.05),and calcification(χ^(2)=3.606,P<0.05),but there was no significant difference in tumor cystic degeneration,surrounding bone destruction,and marginal enhancement between the two groups(P>0.05);(3)MSCT contrast-enhanced scan:pleomorphic adenoma showed progressive enhancement,W-arthin tumor showed"fast in and fast out"enhancement in arteriovenous phase,basal cell adenoma was characterized by significant continuous enhancement,mucoepidermoid carcinoma showed"fast in and fast out"enhancement in malignant tumor group,and most of other malignant tumor cases were characterized by continuous enhancement.Conclusions:MSCT plays an indispensable role in the diagnosis of benign and malignant tumors in the parotid deep lobe,and the accuracy of diagnosis can be improved by combining enhanced scanning.
