A Case of Type III Cystic Sacrococcygeal Teratoma

Abstract

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 × 1 cm coccygeal cyst posterior to the anus. Magnetic resonance imaging (MRI) demonstrated that a 10 × 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.

Three‐dimensional power Doppler sonography in the diagnosis of a cystic sacrococcygeal teratoma mimicking a meningomyelocele: A case report

“…1,3 However, cystic SCT may be misdiagnosed as anterior sacral meningomyelocele, especially when presenting as a posterior cystic mass. [4][5][6] We report a case in which three-dimensional (3D) power Doppler sonography (PDUS) was helpful for making a correct prenatal diagnosis of a type 1 cystic SCT mimicking a meningomyelocele.…”
