由于超高压射线的应用及照射技术的改进,鼻咽癌放疗生存率已有显著提高,但合并放射性脑损伤会影响患者生存质量。作者最近发现鼻咽癌放疗后反复癫痫发作经CT扫描证实为放射性脑坏死1例,现报告如下: 病例:男,43岁,1973年4月20日主诉反复咯血伴右耳听力下降3月余,经外院鼻咽部活检证实为鼻咽癌转来放疗。患者以往体健无癫痫发作史。查体:一般情况良好,双侧颈部无淋巴结肿大,心肺及肝脾等均无异常发现。鼻咽顶后壁约1×1cm~3菜花样肿物。无颅神经损害征。病理为鼻咽未分化
Due to the application of ultra-high pressure rays and the improvement of radiation technology, the survival rate of radiotherapy for nasopharyngeal carcinoma has been significantly improved, but combined radiation brain injury will affect the quality of life of patients. The author recently found that repeated epileptic seizures after radiotherapy for nasopharyngeal carcinoma were confirmed by CT scan as radioactive brain necrosis in 1 case. The report is as follows: Case: Male, 43 years old, complained of repeated hemoptysis and hearing loss in the right ear on April 20, 1973, more than 3 months , confirmed by the nasopharyngeal biopsy of the external hospital for nasopharyngeal carcinoma radiotherapy. The patient had a history of no seizures. Physical examination: In general, there was no lymphadenopathy in both necks, and no abnormalities were found in heart, lung, liver and spleen. The posterior wall of the nasopharynx is approximately 1 x 1 cm to 3 cauliflower masses. No sign of cranial nerve damage. Pathologically undifferentiated nasopharyngeal
