ABSTRACT
A case of massive hydramnios involving a twin-twin transfusion syndrome is presented
with death of the larger twin and the development of hydrops fetal is in the surviving
smaller twin. The amniotic fluid volume of the surviving twin became normal and the
hydrops fetal is resolved spontaneously in utero. Concomitant with the resolution
of the hydrops fetal is, the umbilical cord systolic to diastolic ratio improved.
At the time of delivery, the hydrops had resolved. The liveborn infant died 11 days
later secondary to pulmonary hypertension and cardiorespiratory failure. Although
the fetal status improved in utero, the pulmonary hypertension postdelivery resulted
in neonatal death.
