Prenatal Sonographic and MR Imaging of Extensive Fetal Lymphangioma of intralesional bleomycin, sclerotherapy with OK-432, or percutaneous embolization with Ethibloc (2, 11). The suc- cessful intrauterine treatment of a cystic hygroma with OK-432 has also been reported (12). In conclusion, prenatal MR imaging was valuable in the detection, characterization, and exact evaluation of the ex- tent of an extensive fetal lymphangioma, and complement- ed the role of sonography.
