Prenatal sonographic diagnosis of an extensive fetal axillary hemangiolymphangioma

Hemangiolymphangiorna (HL) is an extremely rare malformation of both the lymphatic and blood vessels. We present a case of fetal axillary HL that was diagnosed sonographically at 36 weeks' gestation. Sonographic examination revealed a large, multilocular, cystic mass consistent with lymphangioma. At birth, a giant hemangioma was noticed involving the right hemitruncus. Based on clinical and sonographic findings, a diagnosis of HL was made. Surgical treatment was considered but was refused by the parents. The neonate died at 14 days of age, possibly due to an intralesional hemorrhage. (c) 2007 Wiley Periodicals, Inc.
