Abstract
Between 1977 and 1987, 8 cases of parapharyngeal space tumor (2 cases of pleomorphic adenoma, and schwannoma, respectively, a case of neurofibroma, neuroblastoma, retension cyst and branchial cleft cyst) were treated in our clinic. There were 4 males and 4 females. This papar reports these cases and discusses the availability of MRI diagnosis. We consider that the x-ray CT is presently most useful for the parapharyngeal space tumor. Howerer, MRI imaged tumor clearly without bone artifacts such as recognized in x-ray CT, and be able to take a information of tumor vascularity. So that MRI is very useful for diagnosis of parapharyngeal space tumor.
