Intrapericardial teratoma as a cause of fetal death--a case report.

TLDR: A large number of intrapericardial tumors go undetected during prenatal diagnostics, until they are found as a cause of intrauterine death or postnatal cardiorespiratory insufficiency, as in this case report.

Abstract: Intrapericardial teratoma is a rare congenital tumor that without treatment leads to cardiac failure in either the prenatal or postnatal period. Early diagnosis and recent surgical advances can, in some cases, delay development of intrauterine symptoms and allow final treatment through a tumor resection. However, a large number of intrapericardial tumors go undetected during prenatal diagnostics, until they are found as a cause of intrauterine death or postnatal cardiorespiratory insufficiency, as in our case report. An abortion was induced in the 23rd gestational week because there was no cardiac activity detected during a routine ultrasound scan in a 35-year old woman. The tumor was found during the postmortem of the fetus.
