Prenatal Ultrasound Findings of Fetal Neoplasms

Abstract

A variety of neoplasms can develop in each tetal organ. Most fetal neoplasms can be detected by careful prenatal ultrasonographic examination. Some neoplosms show specific ultrasonographic findings suggesting the differential diagnosis, but others do not. Knowledge of the presence of a neoplasm in the fetus may alter the prenatal management of a pregnancy and the mode of delivery, and facilitates immediate postnatal treatment. During the last five years, we experienced 32 cases of fetal neoplasms in a variety of organs. We describe their typical ultrasonographic findings with correlating postnatal CT, MRI, and pathologic findings.

The majority of infants was delivered near term, although cases with teratoma were frequently associated with preterm birth (77.8%).…”

The value of early recognition of fetal lymphangioma

“…At USS, the fluid may be anechoic or there may be variable internal echoes or fluid‐fluid levels, due to bleeding and fibrin deposition 12 . In this case, USS and MRI precisely identified the lymphangioma.…”
