A 23-year-old obese woman presented with papilledema. Computed tomography showed no intracranial mass lesions and lumbar puncture revealed an increased opening pressure, confirming the diagnosis of pseudo-tumor cerebri. Standardized echography of the optic nerves was performed immediately before and after lumbar puncture. A marked reduction of cerebrospinal fluid pressure correlated with a decrease in the subarachnoid fluid of the optic nerve sheath.
一名23岁的肥胖女性出现视乳头水肿。计算机断层扫描显示无颅内占位性病变，腰椎穿刺显示初压升高，确诊为假性脑瘤。在腰椎穿刺前后立即对视神经进行标准化超声检查。脑脊液压力显著降低与视神经鞘蛛网膜下腔液体减少相关。
