Ultrasonography is screening modality of choice and plays an important role in prenatal diagnosis of various diseases and neoplasm of fetus. Recently, Magnetic Resonance Imaging was used as a diagnosis tool to fetal disease. We would like to evaluate efficacy of ultrasonography and magnetic resonance imaging for the diagnosis of fetal abdominal solid tumor. METHODS: Among 2,055 cases of abnormal ultrasonography findings detected by prenatal ultrasonography from January 1996 and June 2002, a comparison between the diagnosis made by prenatal ultrasonography, fetal magnetic resonance imaging (MRI), postnatal radiological studies and histopathologic studies was made in four cases with fetal abdominal solid tumor. RESULTS: The first case was diagnosed as adrenal tumor or hepatic tumor by US, hemangioedothelioma of liver by fetal MRI, and confirmed as hemangioendothelioma postnatally. The second case showed concordance with mesoblastic nephroma among the diagnosis made by US, fetal MRI, and postnatal histopathologic studies. The third case was diagnosed as extrathoracic pulmonary sequestration by US and MRI, and the same diagnosis was made by postnatal histopathologic studies. The fourth case was suspected as kidney tumor by US and was diagnosed as adrenal as adrenal neuroblastoma postoperatively. CONCLUSION: Fetal solid tumor is not a common disorder, but the location, size and orgin of tumor plays important role in the prognosis of neonatal period; additional workup by fetal MRI would improve the diagnosis of such tumors.
