OBJECTIVE: To report a new type of sirenomelia in early pregnancy, which was different from the reported types.
CASE REPORT: A 33-year-old Chinese pregnant women (gravida 1 and para 1) attended our hospital in early pregnancy for a routine prenatal ultrasound screening. The Ultrasonography showed fused lower extremities that moved at unison. Two femurs in the thigh were present, while the tibias and fibulas were absent. The right upper limb was not confirmed, with a soft tissue mass located in the right upper limb region. In addition, it revealed an anechoic structure in the posterior cervical region initially diagnosed as cystic hygroma. There was only one umbilical artery and one umbilical vein visible within the umbilical cord.
CONCLUSION: A new type of sirenomelia was diagnosed through 2D and 3D Ultrasonography in early pregnancy, which was different from the reported types and was then considered as a new subtype.
