Objective To evaluate the correlations between MRI manifestations of parapharyngeal space neoplasmsand its pathological findings,and, and to improve diagnostic levels. Methods Thirty-three patients (male [n=19], female [n=14]) with with tumors in the parapharyngeal space were retrospectively evaluated during this study from June 2006 to May 2013. All the patients have pathological diagnosis and were examined by MRI.In all the 33cases, 4 tumors were pleomorphic adenoma,8 tumors were schwannoma, 1 tumor was carotid body tumor, I tumor was Paraganglioma, 2 tumors were Angioma, 3 tumors were carcinoma in pleomorphic adenoma, 1 tumor was pleomorphic adenocarcinoma, 1 tumor was lymphoma, 1 tumor was plasmacytoma, 2 tumors wereparotid gland carcinoma, 2 tumors wereadenoid cystic carcinoma of parotid gland, 1 tumor was acinic cell carcinoma, 1 tumor was malignant peripheral nerve sheath tumor, 2 tumors were synovial sarcoma, 1 tumor was rhabdomyosarcoma, 1 tumor was mucinous adenocarcinoma, 1 tumor was low differentiated adenocarcinoma, 1 tumor was hemangiopericytoma. All patients had plain MRI scan, 32 patients hadconventional enhanced MRI scan, and to compare imaging characteristics of MRI with the pathologicalresults. Statistical analysis was performed with the chi-square test. Results the overall accuracy of plain MRI scanand conventional enhanced MRI scan respectively 51.5% and 78.1%. Conclusion Plain MRI scan combined with conventional enhanced MRI scan can improve diagnostic and differential diagnostic accuracy of parapharyngeal space neoplasms.
