Hepatic rupture is a rare complication of severe preeclampsia with few cases having been reported in the literature. Most liver hematomas with subcapsular rupture occur antenatally but can occur in the postpartum period as well. Liver hematomas are a serious complication of severe preeclampsia but can be managed conservatively if the patient is stable. Hepatic rupture is a medical emergency and can be fatal if not properly diagnosed and treated. Sonography is an effective means of aiding in the diagnosis. Surgical intervention with delivery of the fetus and hepatic repair is essential for survival.

Congenital cardiac masses are rare, with rhabdomyoma being the most common cardiac tumor occurring in the fetus. Intrapericardial teratomas are the second most common congenital cardiac mass, although reports of prenatal diagnosis in the existing literature are rare. Rapid growth of pericardial teratomas usually occurs after 20 weeks’ gestation, resulting in pericardial effusion and hydrops fetalis. Fetuses diagnosed with pericardial teratomas have a poor prognosis, with surgery being the only definitive treatment option.

The presence of a goiter in the fetus is an indication of maternal thyroid dysfunction. It carries an increased morbidity and mortality for the fetus and into the neonatal period. Maternal thyroid disease must be monitored closely and medications adjusted throughout pregnancy to prevent adverse outcomes. In females with poorly controlled thyroid disease, sonography is useful in the evaluation of the fetus at risk for goiter.
