Abstract
|
|
|
Most cystic hygroma or fetal cystic lymphangiomas are congenital non-malignant malformations of lymphatic vessels,
usually occurring around the head and neck region. Their prognoses differ according to the time of detection, associated
chromosomal anomaly, congenital malformation, and size and invasion depth of the mass. They are usually slow-growing but, infrequently, can resolve or shrink spontaneously. However, rapid growth may occur, as well. Cystic hygroma found by antenatal ultrasonography can grow larger and have poorer prognosis. So cystic hygroma must be thoroughly evaluated whether there are associated chromosomal anomalies or congenital malformation, how large and deep it is, and its natural progression, to predict prognosis and to plan a treatment. Antenatal MRI can especially be useful in evaluating cystic hygroma. We report one case in which fetal cystic hygroma was evaluated by ultrasonography and MRI and was successfully managed conservatively.
