title: Mesoblastic nephroma: prenatal ultrasonographic and MRI features.
abstract: Antenatal detection of mesoblastic nephroma by US is possible. Reviewing the literature, we found 19 previously reported cases, only 1 of which underwent prenatal MRI. We present a further case diagnosed by US and confirmed with MRI. The imaging findings and differential diagnoses are discussed. Early and correct detection of this rare entity is of great interest, as it may facilitate prevention and management of severe obstetric and neonatal complications such as polyhydramnios and prematurity. MRI can help to evaluate the origin and the morphological features of a fetal abdominal mass.
