Choroid plexus cysts are typically incidental, asymptomatic cysts. They have been reported to hemorrhage and grow, causing symptoms of obstruction. However, growth and multiplication has not been reported following ventriculoperitoneal shunt procedures. A 66-year-old woman initially underwent a suboccipital retrosigmoid craniotomy for resection of a large petroclival meningioma. Preoperatively, the patient had hydrocephalus. After surgery the patient required a ventriculoperitoneal shunt. Two years after the initial shunting procedure, imaging demonstrated significant growth of new bilateral choroid plexus cysts as compared with pre-shunt imaging. Post-shunt imaging also demonstrated evidence of diffuse dural enhancement characteristic of intracranial hypotension. Despite radiographic growth and multiplication of the cysts, the patient was clinically asymptomatic and had a good neurological outcome.
脉络丛囊肿通常是偶然发现的无症状囊肿。据报道，它们会出血并生长，导致梗阻症状。然而，脑室腹腔分流术后尚未有囊肿生长和增多的报道。一名66岁女性最初接受了枕下乙状窦后开颅手术，以切除一个大型岩斜脑膜瘤。术前，患者患有脑积水。手术后，患者需要进行脑室腹腔分流术。在初次分流术后两年，影像学检查显示，与分流术前的影像相比，新出现的双侧脉络丛囊肿显著增大。分流术后的影像还显示出颅内低压特有的弥漫性硬脑膜强化迹象。尽管囊肿在影像学上有增大和增多，但患者临床上无症状，神经功能预后良好。
