目的:探讨CTS对腮腺肿块的诊断价值。材料与方法:50例腮腺区肿块,其中46例经手术病理证实,4例经临床消炎治疗证实,均做了CT平扫与增强扫描及CTS扫描,对CT与CTS表现结合病理进行分析。结果:一、CT示33例恶性征象结节灶与团块灶,CTS示17例为局限炎性肿块,15例腺内恶性肿瘤,1例腺外横纹肌肉瘤,手术病理证实1例粘膜相关淋巴瘤误为炎性肿块。二、CT示12例良性肿瘤征象。CTS示11例为良性肿瘤,1例恶性肿瘤,有2例误为良性肿瘤,手术病理证实是腺样囊性癌和腺内淋巴结核。结论:CTS对腮腺局限炎性肿块与恶性肿瘤的鉴别比CT及其它影像有独特的优势,对良恶性肿瘤的鉴别有重要价值,且有进一步组织学定性的意义。
Objective: To investigate the diagnostic value of CTS on parotid mass. MATERIALS AND METHODS: Fifty cases of parotid gland masses were observed. Forty-six of the parotid gland masses were proved by operation and pathology. Four cases were confirmed by clinical anti-inflammatory treatment. CT scan and contrast-enhanced CT scan were performed. CT and CTS combined with pathology were analyzed. CT showed 33 cases of malignant signs of nodules and clues, CTS showed 17 cases of localized inflammatory mass, 15 cases of glandular adenocarcinoma, 1 case of extranodal rhabdomyosarcoma, surgical pathology confirmed a case of mucosa-associated lymph Tumor mistaken for inflammatory mass. Second, CT showed 12 cases of benign signs of the tumor. CTS showed 11 cases of benign tumors, 1 case of malignant tumors, 2 cases mistaken for benign tumors, surgical pathology confirmed adenoid cystic carcinoma and glandular lymph node tuberculosis. Conclusions: CTS has unique advantages over CT and other imaging in distinguishing the parotid localized inflammatory mass from malignant tumors. It is of great value in differentiating benign and malignant tumors and has the significance of further histological characterization.
