Answer:
NON IMMUNE HYDROPS -CYSTIC HYGROMA WITH LIMB REDUCTION DEFECT
Findings:
ANTENATAL USG SHOWS SINGLE ANOMALOUS FETUS OF GESTATIONAL AGE 17 WEEKS , AND FETUS SHOWS FOLLOWING FINDINGS: CYSTIC HYGROMA WITH HYDROPS FETALIS SINGLE FOREARM BONE WITH LIMB REDUCTION DEFECT.
Discussion:
Ultrasonography remains the cornerstone of fetal imaging in fetuses in whom cystic hygroma with hydrops fetalis is suspected. The classic finding in cystic hygroma is a cystic mass with multiple septa that appears as multiple, asymmetrical, thin-walled cysts related to the posterior aspect of the neck. These masses are associated with aneuploidy. If the hygroma is large, the cysts can extend to the lateral or even to the anterior aspects of the neck . In our case, it is unique ,because it was associatedwith single forearm bone in left limb with absent hand. DD Fetal cystic hygromas should be differentiated from posterior encephaloceles , in which an underlying skull defect is present, and from cervical myelomeningoceles, in which an underlying vertebral defect is present.
