Prenatal diagnosis of cavernous lymphangioma of the arm.

We present a case of prenatal diagnosis of a fetal cystic hygroma of the arm diagnosed using ultrasound scanning in the 32nd week of gestation. This represents the first reported case of cystic hygroma in this location. Ultrasonography was useful for the assessment of fetal arm mobility and for monitoring the volume of the mass during the pregnancy.
