患者女,18岁。因头痛、呕吐、视物模糊1月入院。内科检查正常。神经系统检查:双眼底视乳头边界不清,生理凹陷消失,有出血、渗出。左侧戈登氏征阳性,颈有轻度抗力。余无异常发现。病后三次CSF检查发现压力均高于2.5kPa,常规、生化检查正常;未发现结核及霉菌,寡克隆区带阴性。两次Hb测定分别为84g/L和85g/L,细胞外铁阴性,铁粒幼红细胞2%,骨髓图示增生活跃。颅脑CT扫描未见异常。经股动脉插管右颈总动脉造影,动脉及静脉期均正常。经输血一次(300ml)及补铁治疗后头痛,呕吐消失,视力恢复,视乳头水肿明显减轻,其余阳性体征均消失。血红蛋白升至98g/L。腰穿CSF压力正常。讨论:贫血所致的颅内压增高并不少见,但大多数
Patient female, 18 years old. Due to headache, vomiting, blurred vision in January admission. Medical examination was normal. Nervous system examination: the bottom of the binocular view of the unclear border, disappearance of physiological depression, bleeding, exudation. Gordon’s sign on the left positive, mild neck resistance. I found no abnormalities. After three CSF CSF tests found that the pressure was higher than 2.5kPa, routine, biochemical tests were normal; no tuberculosis and mold, oligoclonal band negative. The two Hb determinations were 84 g / L and 85 g / L, respectively, with extracellular iron negative, 2% of erythroblasts in erythrocytes and hyperplastic bone in the bone marrow. Brain CT scan showed no abnormalities. The femoral artery catheterization right carotid artery angiography, arteries and veins were normal. After a transfusion of blood (300ml) and iron treatment after headache, vomiting disappeared, visual acuity, optic disc edema significantly reduced, and the remaining positive signs disappeared. Hemoglobin rose to 98g / L. Lumbar CSF pressure is normal. Discussion: anemia caused by increased intracranial pressure is not uncommon, but most
