20例误诊为神经系统疾病的鼻咽癌临床及病理

目的：分析误诊为神经系统疾病的鼻咽癌患者的临床表现，病理改变及误诊原因。方法：对２０例误诊为神经系统疾病的鼻咽癌进行回顾性调查，其中１４例行活体组织检查，６例行鼻咽部ＣＴ和／或ＭＲＩ平扫加增强。结果：头痛是鼻咽癌患者最早期和最常见的症状（占８０％），其次为复视（占５０％）、耳闭塞感、听力减退和盐衄（各占４０％）等。病理类型以及未化化癌（５０％）和鳞状细胞癌（４３％）居多。鼻咽部ＣＴ／ＭＲＩ检查有利于鼻咽癌的早期诊断。结论：鼻咽部检查应作为可疑病例的一种常规检查，同时取活检，以提高鼻咽癌的早期诊断率。

Clinicaland pathological analysis on 20 patients with nasopharyngeal carcinoma were misdiagnosedas nervous systemic diseases

Objective: To study the clinical feature, pathological characteristics and misdiagnosed cause of patients with nasopharyngeal carcinoma misdiagnosed as nervous systemic diseases. Methods: Retrospective study is used to investigate 20 patients with nasopharyngeal carcinoma misdiagnosed nervous systemic diseases and biospy is performed on 14 of them. Results: Headache is the earliest and most common symptom(80%),the following is diplopia (50%), nasal obstructional sense, hearing decline and rhinorrhagia et al. Undifferentiated type and squamous carcinoma occupy most part of pathological type. CT or MRI on nasopharyngeal is beneficial to get early diagnosis on nasopharyngeal carcinoma. Conclusion: Nasopharyngeal examination should be used as a ordinary method on questionable cases, while biospy is performed to increase the early diagnosis rate.
