We present a case of a 29-year-old female complaining of right-sided watery nasal discharge. Radiological investigations identified an intrasphenoidal meningocele. The origin of the meningocele was pinpointed to the right parasellar region and was confirmed surgically. The parasellar bony defect appeared to be due to persistence of the lateral craniopharyngeal canal (Sternberg's canal). Therefore, we assume a congenital origin for the intrasphenoidal meningocele found in the patient. Acquired bony defects of the sphenoid sinus are unlikely at the fusion planes of the different sphenoid bone components. Knowledge of the complex ontogeny of the sphenoid bone is an important key to differentiating between congenital and acquired sphenoid sinus meningoceles.
我们报告一例29岁女性，主诉右侧水样鼻分泌物。影像学检查发现蝶窦内脑膜膨出。脑膜膨出的起源定位于右侧鞍旁区域，并经手术证实。鞍旁骨质缺损似乎是由于外侧颅咽管（施特恩贝格管）持续存在所致。因此，我们认为该患者蝶窦内脑膜膨出为先天性起源。在蝶骨不同组成部分的融合平面处，蝶窦获得性骨质缺损不太可能发生。了解蝶骨复杂的个体发生过程是区分先天性和获得性蝶窦脑膜膨出的重要关键。
