We present the case of a fetal intrathoracic cyst (2.8 x 1.7 mm) detected at 9 weeks and 2 days of gestation. At 11 weeks and 2 days of gestation, cystic hygroma (nuchal translucency = 5.8 mm) with generalized skin edema was identified. HDlive silhouette clearly revealed the location of the intrathoracic cyst. HDlive Flow with HDlive silhouette clearly showed the spatial relationships between the fetal heart and intrathoracic cyst at 13 weeks and 2 days. Cystic hygroma with generalized skin edema was resolved at this time. Chromosome analysis with amniocentesis revealed a normal karyotype (46XY) at 16 weeks and 4 days. The cyst disappeared at 22 weeks and 2 days. The mother delivered a viable, healthy male newborn at 40 weeks and 2 days of gestation. To the best of our knowledge, this is the first report of diagnosing a fetal intrathoracic cyst at 9 weeks of gestation.
