    Abstract:
    An enlarged fetal spleen can be associated with fetal infection, anemia and different syndromes but its prenatal diagnosis is rare. We report on a diagnosis of splenomegaly at 32 weeks' gestation in a fetus which was found to be affected by cytomegalovirus infection. An enlarged spleen was suspected when the stomach was found to be displaced anteriorly and medially and the diagnosis was supported on visualization of the splenic vessels by color and three-dimensional power Doppler ultrasound. The patient had been referred because of fetal growth restriction and intracerebral anomalies and the additional finding of splenomegaly was highly suspicious for cytomegalovirus infection. This was confirmed by positive maternal serology and by neonatal virus excretion in urine. Retrospectively, examination of stored blood samples from 9 and 23 weeks' gestation revealed an early cytomegalovirus infection. Antenatal and neonatal magnetic resonance imaging examinations showed microcephaly, lissencephaly and the presence of microcalcifications. At the age of 9 months, the child suffers from severe neurological impairment and blindness due to severe optical atrophy. This case emphasizes that color Doppler and three-dimensional power Doppler ultrasound can facilitate the antenatal diagnosis of splenomegaly and can help to delineate the spleen from the similar-looking neighboring liver.
