We report a rare case of congenital type III cystic teratoma that may be falsely diagnosed as an anterior sacral meningocele. A female newborn baby presented with a long, white-colored 4 x 1 cm coccygeal cyst posterior to the anus. Magnetic resonance imaging (MRI) demonstrated that a 10 x 4 cm elliptical intrapelvic and -abdominal mass anterior to the sacrum and coccyx extended inferiorly to the retrorectal space. We intraoperatively found that the cyst consisted of a mostly thin, white wall, but also with small posterior narrow nodules. We suggest that all cysts in the sacrococcygeal area should be excluded from teratoma carefully, with MRI.
我们报告了一例罕见的先天性III型囊性畸胎瘤，它可能被误诊为骶前脊膜膨出。一名女新生儿在肛门后方有一个长4厘米、宽1厘米的白色尾骨囊肿。磁共振成像（MRI）显示，在骶骨和尾骨前方有一个10厘米×4厘米的椭圆形盆腔内和腹腔内肿块，向下延伸至直肠后间隙。我们在手术中发现，囊肿主要由薄的白色壁组成，但也有小的后部狭窄结节。我们建议，对于骶尾区域的所有囊肿，应通过MRI仔细排除畸胎瘤。
