title: [Immature intrapericardial teratoma: a case report in a newborn].
abstract: We report the case of an intrapericardial teratoma, diagnosed at 38 weeks of gestation. Echocardiography revealed a 38 x 39 mm multicystic pedunculated mass compressing the right atrium and the right ventricle, but without symptoms, associated with severe anterior pericardial effusion. Surgical resection of the mass was performed after birth successfully. The histological description of the tumor after excision was reported an immature multicystic teratoma grade 2 of 3, with immature neural tissue and without yolk sac tumor cells. The baby had a favorable postoperative course.
