Popis: Introduction Our objective was to evaluate the outcome of fetuses with first and second-trimester fetal cytomegalovirus infection (CMVi) according to prenatal imaging patterns, especially fetuses presenting with mild imaging features (MF), being currently of uncertain prognosis. Material and Methods Among a retrospective study on 415 suspected CMVi cases, 59 cases were confirmed CMVi. Among prenatal imaging features, microcephaly, cortical disorder and cerebellar hypoplasia as well as severe IUGR and fetal hydrops were considered as severe imaging features (SF). Others imaging features were considered as mild imaging features (MF).Postnatal outcome was classified as "normal outcome", “mild sequelae” characterized mainly by sensorineural disorder (SND) and “severe sequelae” characterized by cognitive impairment. Results Only first-trimester (T1) and second-trimester (T2) CMVi cases were included in our study (n=49) since all third-trimester cases (n=10) had normal imaging and outcome. Sixteen fetuses had normal prenatal imaging and normal outcome , except one showing SND. Abnormal ultrasound findings were present in 33 fetuses, including SF noted in 16 fetuses, related exclusively to first trimester CMVi and 17 fetuses with MF (13 during first trimester and 4 during second trimester). Termination of pregnancy (TOP) was performed in 18 cases. Twelve first-trimester infected fetuses presented SF, whereas 6 fetuses (T1: n=5, T2: n=1) presented isolated MF. Four foetal deaths were encountered. Live-born babies with abnormal imaging included 10 foetus with MF and one with SF. Among the 10 live babies with isolated MF, SND was encountered in 5 cases, whereas 5 children demonstrated normal outcome. Overall, 50% of our babies showing MF suffered from SND. No case of cognitive disorders were reported in babies showing only MF. Conclusion SF were encountered only in first-trimester CMVi and should be distinguished from MF. Among our 10 live babies with prenatal MF following first or second-trimester infection, 50% showed SND whereas none presented severe sequelae. In 16 foetuses displaying normal foetal imaging, SND was encountered in one first-trimester case (6%).
