Abstract

Objective To study multislice CT value in the diagnosis of parotid pleomorphic adenoma. Methods Retrospective analysis of 2014 to 2016, confirmed by surgery and pathology of 20 cases of parotid pleomorphic adenoma patients, summarize the CT imaging characteristics, combined with the literature data，further increase of multislice CT in the diagnosis of parotid pleomorphic adenoma accuracy. Results A total of 20 patients found 26 lesions, 19 cases of unilateral and single lesion,1 case is unilateral multiple lesions. 5 cases with shallow lobe. 15cases of density is uniform, 15 cases with uneven density of capsule. Scan the highest density of 41.6 HU, the minimum density of 26.7 HU, an average of 36.1 HU. Enhanced scanning are uniformly 8 cases of reinforcement, 12 cases of non-uniform reinforcement. Conclusion Multislice CT scan and enhanced scan in parotid pleomorphic adenoma diagnosis are of great value in diagnosis and differential diagnosis.
