腮腺造影螺旋CT检查在腮腺肿物诊断中的应用

摘要

回顾分析51例腮腺肿物患者应用腮腺造影螺旋CT检查并重建,结果与病理比对,总结影像特点.其中,结合肿瘤的形态特点和位置特征,对15例多形性腺瘤和15例腺淋巴瘤术前正确诊断;4例恶性肿瘤(恶性多形性腺瘤1例,腮腺鳞癌1例,黏液表皮样癌1例,腺样囊性癌1例)术前提出恶性诊断,另外4例误诊为良性肿瘤;有2例腮腺区淋巴结误诊为腮腺肿瘤经手术治疗.该方法完成的腮腺肿瘤检查图像显示腮腺肿瘤及导管系统清楚,与周围组织关系判断直观,腺淋巴瘤、多形性腺瘤和典型的恶性肿瘤有一定的影像特征,是一项较为实用的检查手段.%51 patients with proven tumor of the salivary glands were examined by sialogram and spiral computed tomography (CT). CT findings were compared with the pathological results. Correct preoperative diagnosis was obtained in 15 cases of pleomorphic adenoma and 15 cases of parotid adenolymphomas and 4 cases of malignant tumor. 4 cases of malignant tumor were misdiagnosed as benign. In 2 patients lymph node was misdiagnosed as parotid gland tumor before surgery. The CT images may clearly show the tumor, parotid duct system and the surrounding tissues. Parotid adenolymphomas, pleomorphic adenoma and malignant tumors can be shown with image features. Spiral CT is feasible in the diagnosis of parotid tumor.
