Lymphangioma is a rare benign tumor characterized by proliferating lymph vessels and composed of large cyst spaces with endothelium‐lined channels of varying dimensions. The incidence of lymphangioma is approximately one in 6000 pregnancies. Less than 1% of lymphangiomas are purely mediastinal. The great majority of cases are of cystic lymphangioma, but very rarely there is a mixed lesion consisting of multiple cysts of dilated capillary and lymph vessels. We report a case of posterior mediastinal lymphangioma diagnosed at 28 weeks' gestation, in which three‐dimensional ultrasonography was helpful in determining the precise location of the tumor. A Cesarean section was performed at 39 weeks and the tumor was resected on the 5 th day postdelivery; histological examination revealed a mixed cystic lymphangioma. Copyright © 2008 ISUOG.
