Mature glial tissue was seen in the middle ear of a patient with no previous pathologic precedents, and a clinical diagnosis of serous otitis media was made. That anomaly was detected, and its corresponding clinical, roentgenographic, and pathologic findings are described. The results led us to diagnose it as a congenital (spontaneous) encephalocele of the middle ear. To our knowledge, other case of pure congenital encephalocele of the middle ear has been reported.
在一位既往无病理先例的患者中耳中发现了成熟的神经胶质组织，并做出了浆液性中耳炎的临床诊断。检测到了该异常情况，并描述了其相应的临床、影像学和病理学表现。这些结果使我们将其诊断为中耳先天性（自发性）脑膨出。据我们所知，此前尚未有其他单纯性中耳先天性脑膨出病例的报道。
