An encapsulated mass of brain tissue was found in the retroperitoneum of a fetus of gestational week 15 and a boy of age 3 years. The masses possessed fibrous tissue that bound them to the spine and intraspinal connective tissue, respectively, but there was no evidence of direct continuity of the ectopic brain tissue with the normal central nervous system. There was no dysraphism. In our fetal case, possible Foix-Alajouanine anomaly was additionally found. The ectopic neural tissue in the retroperitoneal region may be termed "abdominal brain." In the literature, an identical state has been described in the head (paracranial region) but there are no other records of the paraspinal region. Despite the different locations of the masses (head/paracranial or retroperitoneum/paraspinal), these ectopic brain masses should belong to the same disorder spectrum of the paraneuraxial neural ectopia, a new concept.
在一名孕15周胎儿及一名3岁男童的腹膜后发现了包绕的脑组织团块。这些团块分别具有将它们与脊柱和脊髓内结缔组织相连的纤维组织，但没有证据表明异位脑组织与正常中枢神经系统有直接连续性。没有脊柱裂。在我们的胎儿病例中，还发现了可能的福-阿二氏异常。腹膜后区域的异位神经组织可称为“腹脑”。在文献中，头部（颅旁区域）曾描述过相同情况，但脊柱旁区域尚无其他记录。尽管团块位置不同（头部/颅旁或腹膜后/脊柱旁），但这些异位脑团块应属于副神经轴旁神经异位这一疾病谱，这是一个新概念。
