Objective: To investigate the causes of misdiagnosis of suprasellar arachnoid cysts, analyze its characteristics and put forward the diagnostic basis and differential points. Methods: The clinical data fo 97 cases of suprasellar arachnoid cysts diagnosed and treated in the neurosurgery department of Beijing Tiantan Hospital and Hebei General Hospital from March 2015 to March 2019 were analyzed retrospectively. All patients underwent CT and MRI scans with obstructive hydrocephalus. 13 cases were misdiagnosed, including 7 males and 6 females. First visit age 1-31 years old, with an average age of 6.3 years. There were 10 patients younger than 6 years old. The remaining 15-year-old patients, 31-year-old patients and 26-year-old patients each have one case. 11 cases were misdiagnosed as obstructive hydrocephalus, 2 cases as cystic craniopharyngioma. Results: 13 cases were misdiagnosed and mistreated, 11 cases were treated with intraventricular and abdominal shunt, 9 cases were treated with neuroendoscopy and recovered well. One cases of intracranial hematomas underwent craniotomy again, the hematomas were removed again and the bone slise were decompressed. One case had fissured stable after shunt. There were no operative deaths and no complications in this group. After endoscopic reoperation, CT and/or MRI scans showed that the ventricle narrowed in varying degrees, some of them returned to normal size and the flow of cerebrospinal fluid (cerebrospinal fluid) was unobstruct at the end of magnetic resonance cerebrospinal fluid angiography (MRI) fistula after endoscopic reoperation. Conclusions: The incidence of suprasellar arachnoid cysts is low, it is rare in clinic and it is easy to misdiagnose and mistreate. At present, it is recognized that the best treatment methods are partial resection of endoscope cyst wall, cyst ventricle fistula and third ventricle floor fisthla.
目的： 探讨鞍上池囊肿的误诊原因，分析误诊病例的临床特点、诊断依据和鉴别要点。 方法： 回顾分析了2015年3月至2019年3月，首都医科大学附属北京天坛医院神经外科和河北省人民医院神经外科诊治97例鞍上池蛛网膜囊肿临床资料，所有患者均行CT和MRI扫描，均伴有梗阻性脑积水。97例中13例发生误诊误治，其中男7例，女6例，初次就诊年龄1~31（6.3）岁，6岁以下10例，15岁1例，31岁1例，26岁1例，误诊为梗阻性脑积水11例，误诊为囊性颅咽管瘤2例。 结果： 13例中11例行脑室腹腔分流术，9例无效再次行神经内镜治疗，同时去掉分流管，恢复良好，1例分流术发生颅内血肿再次开颅清除血肿并去骨片减压，1例分流后发生裂隙脑室，给保守观察，2例开颅手术切除病例稳定。本组病例无手术死亡者，无并发症发生。内镜再次手术后病例，CT和（或）MRI扫描示脑室有不同程度缩小，部分恢复正常大小，手术后磁共振脑脊液造影造瘘口处脑脊液流动通畅。 结论： 鞍上池蛛网膜囊肿发病率低，临床上少见，易误诊误治。目前公认最佳治疗方法是神经内镜囊肿壁部分切除、囊肿脑室造瘘和三脑室底造瘘术。.
