Identification of the cause of recurrent meningitis may pose a diagnostic challenge. Evaluation of a patient with recurrent meningitis calls for meticulous review of skull base structures by cross sectional imaging to exclude any underlying anatomical abnormality. Our case highlights the importance of excluding persistent craniopharyngeal duct, a rare but treatable cause of recurrent meningitis. The isolation of in recurrent meningitis may be a clue to the presence of a skull base abnormality. Craniopharyngeal canals have been classified depending on their qualitative and quantitative imaging features. Such imaging based classification is important for identification of patients with associated potential pituitary involvement and also for appropriate surgical planning. Controversy exists as to the approach to surgical treatment of craniopahryngeal duct. The persistent craniopahryngeal duct in our patient was successfully treated by an endoscopic transsphenoidal approach.
确定复发性脑膜炎的病因可能带来诊断挑战。对复发性脑膜炎患者进行评估需要通过横断面成像仔细检查颅底结构，以排除任何潜在的解剖学异常。我们的病例突出了排除持续存在的颅咽管的重要性，这是复发性脑膜炎一种罕见但可治疗的病因。复发性脑膜炎中[此处原文缺失内容]的分离可能提示存在颅底异常。颅咽管已根据其定性和定量成像特征进行了分类。这种基于成像的分类对于识别伴有潜在垂体受累的患者以及进行适当的手术规划很重要。关于颅咽管的手术治疗方法存在争议。我们患者的持续性颅咽管通过内镜经蝶窦入路成功治疗。
