鼻咽癌放射脑损伤是一种严重的后遗症,由于近几年来CT扫描技术广泛应用于临床,因而这种后遗症的发现渐有增加。现将本院1988年发现两例报道如下: 例1、男、49岁,住院号:144057,因右颞头痛、复视及面麻3个月,同时出现记忆力减退、易激动及爱争吵。两个月前还有右耳少许流液,于1988年3月9日入院。1986年2月因患鼻咽癌而在本院按常规放疗,鼻咽部肿瘤量为7450CGy/38次(52天),临床治愈出院。入院检查:T、P、R、BP均正常,鼻咽右侧顶后壁及咽隐窝略饱满,颈淋巴结不大、颅神经右V、Ⅵ受累,眼底无水肿现象。CT扫描:鼻咽右侧顶后壁饱满,蝶窦内软组织影,右侧卵圆孔及破裂孔扩大。右颞叶见一片低密度影,增强后见其内出现一环形强化灶(图1)、右颞骨骨质缺损。诊断:鼻咽 Radiation brain damage in nasopharyngeal carcinoma is a serious sequelae. Since the CT scan technique has been widely used in clinics in recent years, the discovery of this sequelae has gradually increased. The two cases reported in this hospital in 1988 were reported as follows: Case 1, male, 49 years old, hospital number: 144057, due to right ankle headache, diplopia and facial anesthesia for 3 months, with memory loss, irritability and love quarrel. Two months ago there was a little fluid in her right ear and she was admitted to hospital on March 9, 1988. In February 1986, he was treated with routine radiotherapy at this hospital because of nasopharyngeal carcinoma. The tumor volume at the nasopharyngeal was 7450 CGy/38 times (52 days), and he was clinically discharged. Admission examination: T, P, R, and BP were all normal. The right posterior wall of the nasopharyngeal and the pharyngeal recess were slightly full. The lymph nodes were small, the right cranial nerves were V and VI, and the fundus was not swollen. CT scan: The right posterior wall of the nasopharyngeal is full, the soft tissue of the sphenoid sinus, and the right foramen ovale and ruptured hole are enlarged. In the right temporal lobe, a low-density lesion was seen. After the enhancement, an annular enhancement lesion (Fig. 1) and a defect of the right tibia bone were observed. Diagnosis: Nasopharyngeal
