Fetal Axillary Cystic Lymphangioma Detected by Prenatal Ultrasonography

Abstract

Fetal cystic lymphangioma, commonly called hygroma, is formed by multiple cysts ranging from few millimeters to several centimeters in size. Fetal cystic lymphangioma is a rare developmental congenital anomaly of the lymphatic system. Most are found in the neck and axilla, rarely in the retroperitoneum, abdominal viscera, limbs, bones, and cervico-mediastinal area. The prenatal diagnosis of cystic hygroma by ultrasound guidance is commonly localized in the nuchal region. We report a case of rare fetal axillary hygroma that was diagnosed at 27 weeks of gestation and delivered at 37 weeks of gestation.
