This is a 36-year-old patient who had her first ultrasound at 36 weeks.  The examination demonstrated a singleton fetus with normal cardiac activity and fetal movement. The fetal biometry corresponded to the 50th percentile for growth (Hadlock). The placenta was anterior. The amniotic fluid was normal.

Prenatal images. At the superior level of the abdomen, the desplacement of the umbilical vein by a mixed mass. The right superrenal is normal while the left superrenal and the fetal stomach are not seen.

Findings:

The finding was a large mass in the left upper quadrant

The mass itself was solid, probably with some heterogenous/cystic space on its right margin.

These findings suggested a hepatic lesion

Choriocarcinoma[i],[ii]

Focal nodular hyperplasia[iii]

Hemangioma[iv]

Hemangioendothelioma[v]

Multifocal hemangioendothelioma[vi]

Hepatoblastoma[vii], [viii]

Metastases from a maternal bronchial carcinoma[ix]

Teratoma[x]

The differential diagnosis between these various tumor is not always possible and there are few reported cases to compare to. In this case the lesion was demonstrated postnatally to be a hepatic Hepatic hemangioendothelioma

These are the images from the liver at the first day of life.

The ultrasound demonstrated a mixed mass without calcifications with well-defined edges was seen in left lobe of the liver.

In the precontrast computer axial tomography a hypodense heterogeneous lesion was seen in the left lobe of the liver. The lesion takes contrast from the periphery to the center, suggesting the diagnosis of  hemangioendotelioma.

Postnatal examination one and a half months after birth. The corticords treatment began, showing evidence of a shrinking tumor.

Postnatal examination four months after birth. The tumor is reduced with corticord treatment.
