例1:男18岁,40℃高烧一周后4个月双眼视力下降。视力右0.15,左0.04,不能矫正。双视乳头颞侧苍白,视野有中心暗点,抗菌素和类固醇治疗无效。气脑造影空气不能进入视交叉部蛛网膜下腔,桥脑前蛛网膜下腔可见片状影象。CT扫描见桥脑前蛛网膜下腔扩大。脑动脉造影正常。开颅见视交叉部蛛网膜肥厚粘连,将其彻底切除。4个月后右眼视力0.2,左眼0.15。例2:男28岁,腮腺炎后半年左眼视力下降为0.02不能矫正,视乳头颞侧苍白,视野有中心暗点,周边1/3扇形不规则缺损。类固醇治疗无效。气脑造影发现第Ⅲ脑室前肿瘤阴影,CT扫描更明确。开颅见蝶鞍旁左视神经下肿瘤压迫。肿瘤有完整灰白色包膜,破后流出胶状物,病理
Example 1: Male 18 years old, 40 ℃ after a week of high fever 4 months binocular vision decreased. Right vision 0.15, left 0.04, can not be corrected. Binocular temporal nipple pale, central vision dark spots, antibiotics and steroids treatment is invalid. Air-to-air imaging can not enter the optic chiasm subarachnoid space, anterior pia subramania can be seen flaky images. See CT scan anterior subarachnoid space expansion. Cerebral arteriography normal. See the craniotomy cross arachnoid hypertrophy adhesions, its complete excision. Right eye vision after 4 months 0.2, left eye 0.15. Example 2: Male 28 years old, half of the first half of mumps after the visual acuity decreased to 0.02 can not be corrected, optic nerve temporal side of the spot, the center of vision has a dark spot, the surrounding 1/3 fan-shaped irregular defects. Steroid treatment is invalid. Cerebral angiography found Ⅲ shadow before the ventricular tumor, CT scan more clearly. See craniotomy craniotomy next to the left optic nerve tumor compression. The tumor has a complete gray envelope, after breaking out of jelly, pathology
