摘　　要：目的分析鼻咽癌误诊为中耳乳突炎病例的临床以及CT资料,探讨误诊原因。方法本组15例患者先后分别进行中耳乳突骨算法CT扫描和软组织算法CT扫描或利用存储原始数据的光盘进行软组织算法重建。结果15例鼻咽癌患者经临床医师首诊均诊断为中耳乳突炎,首次CT诊断为慢性中耳乳突炎6例,发现并且诊断鼻咽癌伴中耳乳突积液9例;同组第2次软组织算法鼻咽扫描均诊断鼻咽癌伴中耳乳突积液。结论少数鼻咽癌首发临床症状与中耳乳突炎极其相似,首诊极易误诊。临床症状孤立、临床医师诊断武断、CT医师阅片不全面为误诊的主要原因。Objective To analyze the clinic and CT data of nasopharyngeal carcinoma which misdiagnosed as the otomastoiditis,and to study misdiagnosis reasones.Methods For 15 cases eardrum mastoid bone algorithm and soft tissue algorithmwas performed for CT scan.Results 15 cases with nasopharyngeal carcinoma all misdiagnosed as otomastoiditis with CT at the frist examine.6 cases was diagnosed as chronic otomastoiditis at the first time.9 cases were detected and diagnosed as nasopharyngeal carcinoma combined with middle ear mastoid fluidify While all cases were diagnosed as nasopharyngeal carcinoma combined with middle ear mastoid fluidify by soft tissue algorithmwas.Or use the CD-ROM of store raw data to the soft tissue algorithm reconstruction.Conclusion A small number of first clinical symptoms of nasopharyngeal carcinoma is very similar to otitis media,the first diagnosis is easily misdiagnosed.Clinical symptoms in isolation,clinicians diagnosed arbitrary,CT physician incomplete reading film are the main reasons for misdiagnosis.
