We report a case in which there was spontaneous regression of hydrops fetalis. Hydrops was probably caused by fetal infection with parvovirus B19. Anemia and hypokinesia of the heart were also observed. Diagnosis was accomplished by the ultrasound, virus detection in maternal serum, complete fetal blood count, and analysis of hepatic enzymes.
