Table 2 Differential diagnosis of fetal hepatic tumors by prenatal ultrasound [11, 15,16,17,18]
From: Unusual presentation of a case of fetal hepatic mass: a case report
Incidence | Location | TB | Shape | Composition | Echo | CD | PSV | RI | Others | Comp | |
|---|---|---|---|---|---|---|---|---|---|---|---|
hemangioma | 60.3% | in either or both lobes | well-defined | regular | solid lesions with hypervascularization | hypo-, iso- or hyperechogenic | high vascularity | low PSV(< 0.4 m /s) | low RI (< 0.7) | fine granular calcifications | Yes |
hepatoblastoma | 16.5% | more than 60% of the cases arise from the right lobe | well or ill-defined | irregular | solid with poor vascularization | hypoechoic with foci of hemorrhage and necrosis inside | less vascularity | high PSV (≥ 0.4 m /s) | high RI (> 0.7) | coarse and dense calcifications | No |
mesenchymal hamartoma | 23.2% | anywhere in the liver | well-defined | regular | multicystic, multilocular | anechoic | low vascularity | - | - | calcifications | NA |
metastatic malignant tumors | unknown | anywhere in the liver | ill-defined | irregular | multi-focal lesions | hypoechoic | high vascularity | high PSV (≥ 0.4 m /s) | high RI (> 0.7) | solid masses with a bull’s-eye configuration | NA |
