Background and Aims Congenital Cytomegalovirus (CMV) infection can lead to neurological sequelae and sensorineural hearing loss (SNHL). To correlate clinical, auditory and neuroimaging findings in the neonatal period to long-term outcome in congenitally CMV-infected infants.

Methods Congenitally CMV-infected infants born between 2001 and 2011 were clinically evaluated and underwent cranial Ultrasound (cUS), cerebral Magnetic Resonance Imaging (cMRI), fundoscopy examination and auditory brainstem response (BAER) in the neonatal period. Both symptomatic and asymptomatic infants were followed prospectively to assess physical growth, neurological, visual and audiological outcome.

Results Forty-two infants were evaluated. Six of 42(14.2%) infants had symptoms/signs at birth: microcephaly (3), petechiae (4), thrombocytopenia (3), hepatosplenomegaly (3), jaundice (1), elevated serum transaminases (1). Two cases of chorioretinitis and 4 cases of abnormal BAER were found in the neonatal period. cUS demonstrated pathological findings in 6/42(14.2%) infants: ventriculomegaly (4), pseudocysts (3), calcifications (3), cerebellar hypoplasia (1). cMRI showed abnormalities in 10/42(23.8%) infants: pseudocysts (3), white-matter lesions (7), lissencephaly (1), ventriculomegaly (4), calcifications (2), cerebellar hypoplasia (2). At follow-up (mean duration 43±18 months) 8/42(19%) infants showed SNHL and 8/42(19%) showed impaired psychomotor development. The composite outcome (SNHL and/or neurodevelopmental sequelae) was poor in 9/42(21.4%) infants. Neonatal findings in infants with an adverse outcome were: clinical signs (5/9), abnormal BAER (2/9), abnormal cUS (5/9), abnormal cMRI (9/9). Symptomatic infants received antiviral treatment.

Conclusions In our series 21.4% of congenital CMV infected infants had one or more sequelae at follow-up evaluations. A pathological neuroimaging at birth was the most sensitive predictor of long-term sequelae.
