AB Key  PointsSacrococcygeal  teratomas  (SCTs)  arise  from  a  totipotent  stem  cell  in  Henson’s  node.Most  SCTs  are  large,  complex,  solid,  and  cystic  masses  but  may  have  intrapelvic  or  intra-abdominal  extension.Ultrasound  alone  will  make  the  diagnosis,  but  fetal  MRI  will  help  define  anatomic  relations,  and  echocardiographs  will  evaluate  high-output  state.SCTs  that  are  >10  cm,  solid,  highly  vascular,  or  rapidly  growing  are  at  highest  riskfor  hydrops.Fetal  surgery  may  be  an  option  in  cases  that  develop  early  signs  of  hydrops.Cesarean  section  is  usually  indicated  for  large  SCTs  due  to  risk  of  rupture  and  exsanguination.SCTs  are  usually  benign  but  can  have  immature  elements  or  rests  of  malignant  yolk  sac  tumor.Close  serial  follow-up  for  at  least  3  months  for  tumor  recurrence  is  indicated  with  serial  α-fetoprotein  levels,  physical  exam,  and  imaging  studies.
