The authors describe a patient with pseudotumor cerebri syndrome who showed at venography a giant arachnoid granulation in the left dominant transverse sinus and hypoplasia of the contralateral transverse sinus with high pressure proximal to the obstruction. Dilation of the left transverse sinuses with a stent reduced both the pressure gradient across the arachnoid granulation and the cerebral spinal fluid opening pressure with immediate symptomatic improvement, suggesting a causal relationship between venous outflow obstruction and pseudotumor cerebri syndrome.
作者描述了一位患有假性脑瘤综合征的患者，其静脉造影显示左侧优势横窦有巨大蛛网膜颗粒，对侧横窦发育不良，梗阻近端压力升高。支架扩张左侧横窦，降低蛛网膜颗粒跨壁压力梯度和脑脊髓液开放压力，症状立即改善，提示静脉流出梗阻与假性脑瘤综合征之间存在因果关系。
