The prenatal diagnosis of pericardial tumor is extremely rare.
It may have serious consequences such as massive pericardial
effusion, cardiac tamponade, hydrops fetalis and fetal demise.
We present a case of nonimmune hydrops fetalis secondary
to pericardial mass which was successfully treated in utero
by serial pericardiocentesis. Also, we present a review of the
literature regarding the intrauterine interventions performed
in pericardial tumor cases. At 24 weeks’ gestation ascites,
diffuse subcutaneous edema at the thorax and abdomen, scalp
edema and two masses within severe pericardial effusion were
detected. After the pericardiocentesis performed at 25, 28 and
29 weeks’ gestation, ascites and scalp edema resolved, and the
pericardial effusion regressed gradually. The size of masses did
not change throughout the gestation. After the infant was born
at 37 weeks’ gestation, the masses shrunk spontaneously within
