RESUMO
OBJECTIVE: Congenital cytomegalovirus infection (cCMV) is a common, frequently unrecognized cause of childhood disability. The aim of the present study was to determine the symptoms that raise the suspicion of cCMV, define the neurodevelopmental outcomes, and assess their correlations. METHODS: This longitudinal observational study comprised 78 children with symptomatic cCMV who underwent neuropediatric follow-up for 4 to 17.9 years. RESULTS: Symptoms of central nervous system involvement, hearing/visual impairments, and hepatic involvement were mostly recognized. The average age of disease suspicion was 3.3 months. In terms of outcomes, 10.53% of the children developed complex minor neurological dysfunction and 23.68% developed cerebral palsy. Visual and hearing impairments occurred in 38.16% and 14.47% of patients, respectively. Intellectual disability was present in 30.26% of patients, and epilepsy in 21.05%. Microcephaly and hearing impairment was significantly associated with overall neurodevelopmental outcome. Microcephaly was also associated with poor motor outcomes, hearing impairment, and severe visual impairment. Furthermore, microcephaly and intrauterine growth restriction were significantly associated with poor cognitive outcomes. CONCLUSION: Symptoms that raised the suspicion of cCMV-especially microcephaly, hearing impairment, and intrauterine growth restriction-were important parameters that were associated with outcomes; however, their recognition was often insufficient and/or late.

Lenticulostriate vasculopathy (LSV) is an ultrasound (US) visible lesion of the brain, which appears as echogenic streaks or spots in the arteries of thalamus and basal ganglia. LSV has varied etiology. Transfontanelar Color Doppler (TFCD) can easily display lenticulostriatal blood flow and assess: stage I LSV with present flow within echogenic changes and stage II LSV in which the flow disappears, despite a presence of streaks and spots, which at this stage most probably correspond to calcification. The objectives of this study are to determine: (1) Whether there are differences in distribution (unilateral or bilateral) and presence (during first year of age) of TFCD flow between congenital CMV infection positive and negative group of children with LSV (2) Could US and TFCD findings of LSV be an indication for further investigation of possible congenital CMV infection, because of their variable and often adverse neurodevelopmental outcome? We examined and followed-up 98 infants with LSV One group (37/98) with congenital CMV infection and second (61/98) negative. All infants had clinical signs of neuromotor delay and ultrasound and TFCD markers of LSV Our study shows that most of the patients from both groups had TFCD visible flow at the age of 0-4 months. In majority of them in both groups, at the age of 5-8 months, there was no more visible flow. TFCD showed no statistically significant difference among congenital CMV infection positive group and negative group, nor in youngest age period (0-4 months), nor in later course of flow in LSV unilaterally or bilaterally. Although the LSV presents nonspecific marker for intracranial infection (ICI), all infants presenting with LSV should be evaluated for possible ICI. Thus, the Doppler findings of LSV in infants require a detailed examination, monitoring and follow-up of neuromotor outcome.
