Most prenatally diagnosed cases of Congenital Mesoblastic Nephroma (CMN) have been complicated with hydramnion or hydrops fetalis. We report a case of prenatal ultrasound diagnosis of CMN not complicated by hydramnion or hydrops fetalis. The tumor mass was 3.8×4.2×5.0 cm in size in the left abdomen not crossing the medianline, and the outline was clear on ultrasound. The tumor was smaller for birth weight than in other prenatally diagnosed cases of CMN. We speculate that hydramnion or hydrops fetalis is due to the obstrution of circulation caused by pressure of the tumor mass.
