Bronchogenic cysts are congenital malformations derived from anomalous budding of the embryonic foregut. Intraspinal bronchogenic cysts are extremely rare and most of them are extramedullary. There has been only one case of intramedullary spinal bronchogenic cyst reported. We present an 18-year-old male patient with spastic paraparesis and bowel and bladder involvement. MRI revealed a 2 cm diameter intradural and intramedullary lesion at D2-D3 level which was hyperintense on T1 and hypointense on T2 imaging. Histopathological examination after surgical excision of the lesion revealed a bronchogenic cyst. To our knowledge this is the first case reporting an intramedullary bronchogenic cyst at the upper dorsal level and overall second reported case of intramedullary spinal bronchogenic cyst.
支气管源性囊肿是源于胚胎前肠异常芽生的先天性畸形。脊髓内支气管源性囊肿极为罕见，且大多数位于髓外。仅有1例脊髓内支气管源性囊肿的报道。我们报告1例18岁男性患者，有痉挛性截瘫及肠道和膀胱受累。MRI显示在D2 - D3水平有一个直径2 cm的硬膜内髓内病变，在T1加权像上呈高信号，在T2加权像上呈低信号。病变手术切除后的组织病理学检查显示为支气管源性囊肿。据我们所知，这是首例报道的上胸段髓内支气管源性囊肿，也是脊髓内支气管源性囊肿的第二例报道。
