This sign indicates severe, structural central nervous system involvement and is a strong predictor of poor long-term neurodevelopmental outcomes, including intellectual disability and cerebral palsy.
While findings like petechiae, early jaundice, and hepatosplenomegaly are common manifestations of symptomatic cCMV, they represent hematologic or systemic involvement. Microcephaly is the priority because it reflects an irreversible insult to brain development that occurred during the critical period of organogenesis, typically in the first trimester.
Do not dismiss other signs, but prioritize microcephaly. Immediate actions include a thorough neurologic exam, cranial imaging (ultrasound), and audiology screening. Early identification and referral for developmental services are crucial to mitigate long-term disabilities.
